It has full indefinite run-dry capability, a 100,000 B10 bearing life and a high efficiency, low NPSHr, impeller design for good suction lift capability.
With the NPSHr data from the pump manufacturer, it would be necessary to then calculate the net positive suction head available (NPSHa) from the cooling system.
NPSHr (NPSH required) is a characteristic of the pump.
Their high NPSHR capabilities keep fluid moving with less chance of cavitation in processes where a suction lift is required or where a high vapor pressure fluid is being pumped.
Second, laminar flow means low NPSHr (net positive suction head required).
For this reason, manufacturers establish the minimum operating flow as well as listing all of the limiting design conditions, such as net positive suction head required (NPSHR), maximum flow and others.
The suction pressure required to prevent cavitation for a particular pump is indicated as NPSHR and is published on the pump curve.
These close coupled pumps are designed on a modular concept, which ensures a wide range of models and therefore an extensive performance range covering capacities from I to 300 m3/hour at heads up to 100 metres, with low NPSHr. CSF CSD pumps are manufactured in electro-polished investment cast AIS!
Most commercial pumps will have an NPSHR curve included on the same graph as the pump design curve.
Efficient motor-speed operation is achieved with new design concepts for the idler and head while retaining excellent NPSHr characteristics.
Large suction inlets lower the NPSHR since velocity head and entrance losses are decreased.

Facilitating easy handling of large volumes of concrete on placing boom jobs, diversion valves can be used to switch the flow of concrete between towers or, more commonly, for system blow out. Putzmeister offers three types of valves that work as part of its placing systems: DVH – Hydraulic Diversion Valves, GVH – Hydraulic Shut-Off Valves and SVH – Hydraulic Swivel Valves. Each offers multiple ports and can be mounted vertically or horizontally for optimum flexibility.
The DVH 5/2 shown at CONEXPO-CON/AGG is ideal for use with two or more delivery lines while handling high pressures up to 1885 psi (130 bar) without leaking. Featuring five ports and two positions, it easily adapts to job site conditions. It also enables one pipeline to be cleaned while concrete is still being conveyed through another. The valve measures 55"L x 20"W x 31"H. For more complex jobs, multiple diversion valves can be utilized.
Putzmeister also offers GVH – Hydraulic Shut-Off Valves that are pressure-resistant and absolutely leak-proof at high pressures up to 1233 psi (85 bar). The company’s SVH – Hydraulic Swivel Valves can be used as stop valves or with a diversion function and automatically equalize the height difference between the pump outlet and the pipeline on the ground.
Strong, reliable and durable, Putzmeister valves are part of the company’s full line of proven concrete and material placement technologies.

3D MODELLING OF THE WWER 440 HORIZONTAL STEAM GENERATOR
A three-dimensional thermal-hydraulic model and a numerical procedure for the simulation and analysis of steady-state as well as transient operation of horizontal steam generators are presented. The two-fluid
modelling approach is applied for the two-phase flow on the shell side of the steam generator. The model is solved by the SIMPLE numerical procedure, which has been adjusted for the multiphase flow conditions.
The operation of the horizontal steam generator in the WWER 440 nuclear power plant has been simulated at the full load, steady-state condition. Presented results are compared with the data measured at the
NPP Novovoronezh. The agreement is good. Obtained results can be used in plant design or retrofitting, in nuclear power plant safety analyses and as improvement of existing one- dimensional thermal-hydraulics
models of the horizontal steam generator which are assessed by system codes used for the nuclear power plant safety analyses.

PUBLIC NOTICE: Sibley County is proposing roadway reconstruction along CSAH 6, from Henderson to just beyond the CSAH 6/5 intersection and a portion of CSAH 5, from just north of CSAH 6 to the Blakey Bridge, between Henderson and Faxon Township, MN. The CSAH 6 reconstruction seeks to resolve roadway flooding issues along CSAH 6 and CSAH 5. Flooding along the Minnesota River in the project location is occurring more frequently and for a longer duration. The project would address the current flooding issues through a combination of grade raising, culvert work, road reconstruction, and the construction of a filtration basin. The project would also reduce sedimentation maintenance through the construction of a sediment basin to the west of the CSAH 6/5 intersection.

As preparations for removal of the two Elwha River dams continue, Bureau of Reclamation dam managers will again lower the water level in the Lake Mills reservoir to help accelerate erosion along a pilot channel created last fall.
The drawdown will begin within the next several days; managers estimate that the water level will drop approximately one-and-a-half feet each day until the reservoir is six feet lower than normal. This is expected to occur by the end of April. The Lake Mills boat launch will be inaccessible and unusable for the duration of the drawdown. Following the drawdown, the reservoir will be allowed to refill and will reach full pool no later than June 1.
Last fall, contractors completed an erosion-enhancement project at the Lake Mills delta. Over a five-week period in September and October, workers removed trees, created a pilot channel through the middle of the delta and repositioned a logjam to direct the river into the new channel.
Prior to last autumn's erosion-enhancement project, alder trees had overgrown over much of the delta, and large logs had been deposited by the river, stabilizing the sediments that make up the delta. Removing the trees and establishing the pilot channel gave the river a "head start" at eroding the delta. Lowering the reservoir will help maximize that ongoing erosion.
"During the dam removal process, the river will carry large amounts of sediment downstream where it will restore fish habitat, shellfish beds and beaches along the Strait of Juan de Fuca," said Karen Gustin, Olympic National Park Superintendent. "Lowering the reservoir level now will continue to give the river the head start it needs to erode the sediment."
As reservoir levels drop during and after dam removal, the river will naturally erode and carry downstream the sediments that have accumulated in the reservoirs, replenishing downstream spawning beds and the estuary and beaches at the river's mouth.

As an effect of the shortage of rainfall and the closure of Babli project gates in Maharashtra, the river Godavari has almost dried up in Nizamabad district. The fishermen are miserably affected as the water-level is at its low. The river flows up to the Sriram Sagar Project or SRSP in Telangana entering through Kandakurthi village in Renjal Mandal from Maharashtra.
The SRSP project recorded lower water level as much as of 90.31 tmc in its total storage capacity of 1,091 tmc ft. The reservoir was fully stored on the same day last year. The officials of the SRSP project are concerned about the dripping water level in the project, and as an immediate step, the entire outflow to the main canals has been restricted.


December 15, 2020: The Munjoy Stormwater outfall project was completed in conjunction with the Thames Street Extension Project in 2019. The project installed a 60" storm drain outfall line from the seawall at the edge of the new Amethyst Lot park up to Fore Street through the new roadway constructed as part of the adjacent development projects. The project installed 540 linear feet of new 60" storm drain pipe.
The total cost of this project for the roadway extension and the new storm drain system came in at $2,300,000.00.
The new storm drain system will allow DPW to install a new separated storm drain system in Fore Street/Eastern Prom from the 100 Fore Street development driveway to Morning Street. The new separated storm drain system will help reduce combined sewer overflows at CSO location # 23-India Street, which discharges CSO flows adjacent to the Ocean Gateway Marine Terminal. This next phase of the project is currently under design. Funding for this next phase of the work is being requested as part of this year's Capital Improvement funding Request.

Back Pressure Regulators work differently than standard, or pressure reducing regulators,
and it is important to know the difference.
Pressure reducing regulators reduce a higher supply pressure at
the inlet down to a regulated lower pressure at the outlet (downstream).
Back Pressure Regulators work the opposite way. They regulate the higher
inlet (upstream) pressure by opening up only as much as necessary to hold
back the desired pressure at the inlet (upstream).
Back Pressure Regulators work just like relief valves, but the emphasis is on steady
state pressure control instead of on/off pressure protection.
Back pressure regulators are also similar to back pressure valves,
though the term "valve" implies a different control mechanism.

China has undertaken the greatest project since the erection of the Great Wall and the Grand Canal -- the Three Gorges Dam project. The Three Gorges Dam will be the largest hydropower station and dam in the world, with a 1.2 mile stretch of concrete and a 370 mile-long reservoir and 525 feet deep. This project will cost more than virtually any other single construction project in history. The idea of building a dam across the Yangtze river to control flooding and to and to harness it for hydropower has been the dream of several generations of Chinese since the time of Dr. Sun Yat Sen, forerunner of China's democratic revolution. The first proposition for construction dates back to the year 1919, when Dr. Sun Yat Sen suggested to build a dam at the Three Gorges. Since 1954, Chinese and foreign scientists and engineers have devoted themselves to the planning, design and consulting work of the project.
The full-scale construction is currently underway and the projected completion date is 15 years away in the year 2010.
As planned, the capacity of Three Gorges dam, 17 million kilowatts, will top that of the largest dam currently operating by 40 percent. Its projected annual power generation of 84 billion kilowatt-hours is equivalent to a coal mine capacity of 40 to 50 million tons per year. The project will accommodate 1/9th of China's power needs. It will cost (in 1990 prices) as estimated RMB 57 billion ($ 10.57 billion). Once completed, the dam will be 185 meters high and store 39.3 billion cubic meters of water. It will create a reservoir 36 miles long and 525 feet deep.
Supporters say the benefits of the project far outweigh the costs. The principal advantage of the project is to generate power to keep...

Mott MacDonald, in a joint venture with Coyne et Bellier of France, has been appointed by the Water and Power Development Authority of Pakistan as design engineer for an extension project at the Tarbela Dam hydropower project, Mott MacDonald reported.
The project, with finance arranged by the World Bank, will extend the power generation facilities at Tarbela Dam, which is situated on the Indus River, 100 kilometers northwest of Islamabad. The extension is expected to add about 1,000 MW of electrical capacity to the national power system.
The dam, completed in 1974, was designed to store water from the River Indus for irrigation, flood control and the generation of hydroelectric power.
The 148 meter high, 3000 meter long dam has two gated spillways and five tunnels that provide irrigation releases and power generation. At the time of construction the dam tunnels 1, 2 and 3 were scheduled for power generation and tunnels 4 and 5 were designed exclusively for irrigation release.
Mott MacDonald has been appointed on the development of existing tunnel 4 which is to be used for power generation and is likely to add two units of 480 MW each to the scheme. Mott MacDonald will carry out a detailed feasibility study to manage the implementation of the extension so that it does not affect the irrigation release and sediment management. This will also include the modification of intake structure, the construction of a powerhouse and the penstock between the outlet of the tunnel and the new powerhouse.
The project is due for completion around 2016 and has an estimated capital value of approximately US$500 million.
Recently, Mott MacDonald announced it will continue to monitor construction of Pakistan’s 84-MW New Bong Escape hydro project, the first private hydropower development in Pakistan to reach financial close.
Mott MacDonald was appointed as lender’s engineer for a consortium of lenders (Asian Development Bank, Habib Bank Limited, Islamic Development Bank, National Bank of Pakistan, International Finance Corporation and Proparco) on the New Bong Escape Hydroelectric Project in 2005. The project was Pakistan’s first private hydroelectric project to reach financial close (December 2009), Mott MacDonald reported.

For more than 20 years, the City of Jacksonville Beach has experienced serious seasonal flooding along A1A and surrounding streets. As part of a larger team contracted with the FDOT District 2, SAI was responsible for developing a highly detailed stormwater model of a 3.7-square mile area of the City to evaluate the existing flooding condition and develop and optimize various flood mitigation designs. In the area of concern, SR A1A was constructed in a depression between relic sand dunes and the Atlantic Ocean. That fact coupled with an inadequate drainage system results in frequent flooding along this highly trafficked roadway.
SAI originally updated an existing ICPRv3 model to validate the flooding condition and conduct expedited alternatives analyses. However, to better represent the overland flow (as much of the flood flow in the area is characterized), SAI developed a more complex ICPRv4 model that included triangulated 2-D mesh elements with over 22,800 nodes and 65,200 links. This allowed SAI to more accurately represent overland flow and evaluate the designs using animations of flow, flood depth, and flood profiles. In collaboration with the design efforts of the project team, SAI used these model tools to evaluate and optimize approximately 400 design scenarios. These included new intercoastal outfalls, upsizing existing drainage infrastructure, channel regrading, pumping systems, and maintenance improvements. The final design includes replacement of the Kings Road Bridge and regrading and widening the channel. The design also includes the installation of sheet pile wall in the outfall channel and the replacement of the roadway crossings at 4 roads.


Central Tawa Catchment Stormwater Upgrades
On behalf of Wellington City Council, we are working to upgrade the stormwater network in three parts of central Tawa to reduce flooding in the area.
If you have any questions about this work, please contact:
Wellington Water, 04 912 4400
This project is currently in hold.
Why are we doing this?
There has been recent widespread flooding the CBD, Lincoln Ave, Collins Ave, and Beauchamp Street.
These large-scale events are mainly caused by under-sized and/or blocked pipes unable to cope with the large stormwater flows from the steep catchment above central Tawa.
This project will upgrade and increase the capacity and performance of the network to reduce the frequency and impact of flooding on the community.
It is part of a wider programme of stormwater works in Tawa to increase the capacity and improve the resilience and performance of the local stormwater network, reducing the impacts of flooding on the community.
What are we doing?
The project will involve works in three separate areas as follows:
- Collins Avenue Installing a new pipe between Coates Street and Porirua Stream and upgrading the stream channel inlet at Collins Avenue/Coates Street intersection. Duplicating outlet from channel next to railway tracks to new pipe construction under the railway line.
- Lincoln Avenue Installing a duplicate pipe between Lincoln Avenue and Porirua Stream and upgrading the existing stream channel at lower Lincoln Avenue. Localised flood wall protection in two areas.
- Lyndhurst Park Installing a flow device on culvert entrance, construct structural brick wall and bund around clubrooms and field. Use lower field to increase storage and upgrade underdrains. Improve stability of the Lyndhurst Creek bed and bank areas. Upgrade grate at the inlet above the Tawa Commercial Area on the Lyndhurst stream.
The project is in the early design stages.

FORT ST JOHN, B.C. -A new milestone was reached for BC Hydro and the Site C project with the completion of the Peace River diversion tunnel excavations.
The completion of the excavation of the two large diversion tunnels that are located on the north bank of the river was December 24, 2019. According to BC Hydro, the tunnels are approximately 750 metres long and 11 metres in diameter.
BC Hydro shares, that later this year, the tunnels will be used to reroute the Peace River around the dam site, allowing for the construction of the earth-fill dam across the main river channel.
Excavations on the two tunnels began in summer 2018 and breakthrough on the upper half of the tunnels (known as the “crown”) occurred in summer 2019. Since that time, efforts focused on excavating the lower half the tunnels (known as the “bench”).
BC Hydro shares the concrete tunnel lining process is, on average, about 50 percent complete in the tunnels. By using a custom-built slip form that enables concrete to cure in a perfect circle outside the form. At the same time, construction of the structures that will house the inlet gates are nearing completion; construction of the outlet gate structures will be completed once the concrete lining forms have been removed from the tunnels.
According to BC Hydro, they remain on schedule to begin diverting the Peace River in September 2020. River diversion will be in place until the Site C reservoir is filled in 2023.

The second stage of the aqueduct went from Aquilla Lake to Brad Lake.
The elevation at Brad lake is 1370 feet. From 25 miles East of Breckenridge the aqueduct goes W to 19.5 miles ENE of Abilene, a distance of 60 miles . The dam yet to be built will top out at 1840 feet with maximum water level at 1830 feet. The total lift of the water in stage 3 is (1830 – 1370 + 60×2.2) feet = 592 ft. To lift 26,000 cubic feet per second 592 feet requires two 500 MW LFTR nuclear reactors plus use another 100 MW from the Texas grid. The upper Brad Cemetary dam will contain about 90,000 Acre-ft when full, about two days worth of storage. For 5 hours per day these two reactors can provide 1 GW of peak power to the grid. There will be a lower dam to provide hydroelectric power storage of 4 GWh, of 800 MW for 5 hours, after which the lower dam will be re-emptied by pumping back the water to the upper dam.
And this is what a hydroelectric power storage unit looks like:

CSS were engaged as subconsultants by The Balmoral Group USA, to complete the hydrologic and hydraulic analysis for the proposed upgrade of the Fannie Road Bridge crossing of Big Escambia Creek in Escambia County, Florida.
Peak discharges were estimated using regional regression analysis and were verified through application of flood frequency analysis techniques based on Bulletin 17B of the Interagency Advisory Committee on Water Data (1982). Inputs to the regression analysis were extracted from a CatchmentSIM project of the Big Escambia Creek catchment that was developed using LiDAR information. The Big Escambia Creek catchment was determined to occupy a total area of 878 km2.
Flood behaviour along Big Escambia Creek was defined using a two-dimensional hydraulic model that was developed using the RMA-2 software. The RMA-2 model was used to simulate flood behaviour for ‘existing’ conditions as well as ‘proposed’ conditions for 2 different bridge replacement options. Difference mapping was prepared showing the spatial distribution of increases and decreases in peak flood level and flow velocity.
The velocity estimates generated by the RMA-2 model were used in conjunction with detailed geotechnical information to prepare contraction and pier scour estimates. The scour estimates were used to assist in the design of the bridge piers
