Piston Valve Cast 65-200mm (SPL)
Though sealing principle remains same as valve size 15mm to 50mm, pressure acting on large size Piston has been compensated in order to reduce the operational torque. Therefore, Piston is modified to have media pressure same at below and above Piston. This means, effect of media pressure on Piston is nullified thereby making valve operation easy. Two main rings act as seal across ports and two similar rings but small size act as seal to atmosphere. There is one more ring between body/bonnet joint.

The Tapovan Vishnugad power plant is a 520MW run-of-river project being constructed on Dhauliganga River in Chamoli District of Uttarakhand, India. The plant is expected to generate approximately 2,558GWh of electricity per year.
Construction of the hydroelectric power project began in November 2006. Power production from the plant was expected to begin in 2012, but sluggish tunnel excavation works and flash floods in June 2013 delayed its inauguration. The project is expected to commence operations in 2016.
NTPC is developing the project at an estimated cost of approximately INR 29.78bn ($677m).
Tapovan Vishnugad power plant details
The Tapovan Vishnugad hydropower project will consist of four 130MW Pelton turbines, and a barrage constructed across the Dhauliganga River. The barrage will be 200m-long and 22m-high, and will consist of four gates measuring 12m-high and 14m-wide each.
The reservoir is expected to create a catchment area of 3,100km2. It also includes an intake sill located at 5m above the riverbed, at an elevation of 1,787m.
The river water will be diverted into the head race tunnel (HRT) via a desilting basin. The HRT will have a diameter of 5.6m and a maximum discharge capacity of 122.2cm3/s. The tailrace tunnel will be 493m-long and will have a diameter of 7m.
A surge tank at the end of the head race tunnel will be installed to minimise the water hammer during operation. Two pressure shafts with a diameter of 3.6m each will emanate from the surge tank. Each shaft will be bifurcated into two branches of 2.6m diameter penstock and will be to feed water into the turbine.
The project will comprise four D-shaped silt flushing tunnels (SFT) to carry flushing discharge from the desilting basin. A 93m-long D-shaped tunnel (also known as adit) will facilitate the excavation of the SFTs.
Plant construction details
Major works at the Tapovan Vishnugad power project include the construction of the barrage, head race and tail race tunnels, power house, and switchyard.
The head race tunnel package involves the excavation of a 12.1km-long head race tunnel (HRT) and three Adits. Approximately 8.6km of the tunnel will be excavated using a tunnel boring machine with an excavation diameter of 6.57m. The remaining 3.5km section will be excavated using Roadheader and will use drill and blast method, if required, depending on the geology.
The Adits will be excavated using drill and blast method. Ancillary works of the tunnel include the construction of 4.5km of road, and widening/upgrading some of the existing roads.
The construction work was severely affected by the flash floods in June 2013. The diversion tunnel was completely washed away along with the under-construction cofferdam. Approach road to the silt flushing tunnel was also damaged.

Keywords: Dredging efficiency; Sedimentation; Yellow River; Dredging channel
Abstract: According to experimental data, dredging in the lower Yellow River is possible and has some advantages. In general, the dredging efficiency consists of three parts: the scouring and depositing rate (SDR) in the upper dredged channel, the fill-in rate in the dredged channel and the scouring and depositing in the lower dredged channel. The factors affecting dredging efficiency include the dimension of dredged channel and the flow and sediment conditions, and the effects of the latter are larger than that of the former. If the ratio of width to depth of dredged channel was about from 5 to 8, and the length of dredging channel was about 10 km, the dredging efficiency would be the highest in the Lower Yellow River. For the same dimension of dredging channel, the dredging efficiency would decrease rapidly with increase of the ratio of sediment concentration to discharge. When the ratio is about 0.025, the dredging efficiency is better. When the ratio is over 0.05, the dredging efficiency almost disappears.


Evaluation of Hydrodynamic Pressure in Arch Dams Under Earthquakes
The evaluation of hydrodynamic pressures along the upstream face is a critical parameter for the analysis and design of an arch dam. As there are no proper methods available for the evaluation of pressure this paper proposes a new practical procedure to evaluate the hydrodynamic pressure coefficients in arch dams during earthquake by considering the finite element analysis of the impounded reservoir. The arch dam system has been considered to be composed of two substructures, namely the reservoir and the dam. For different combinations of slopes and vertical portion of upstream faces, reservoir systems are derived for twenty different sections. Upstream breaks at depths of 3/4, 1/2, 1/4 of dam heights are introduced. Angles of 150, 300,450 and 600 of variable upstream faces are contemplated for each break. The bottom of reservoir is assumed to be rigid and horizontal. The governing equation with related boundary conditions is implemented in the finite element analysis considering horizontal earthquake components. The reservoir, has been idealized using three and four noded isoparametric finite elements. This procedure enhances the efficiency of seismic assessment of arch dams by reducing the modeling and computational difficulty combined with reservoir discretization while keeping the advantages of conventional finite-element software in conducting seismic analysis.
Key words- Arch dams, Finite Element method, Pressure coefficients, Hydrodynamic pressure.

Aero-fuel centrifugal pumps are important power plants in aero-engines. Unlike most of the existing centrifugal pumps, a combination impeller is integrated with the pump to improve performance. First, the critical geometrical parameters of the combination impeller and volute are given. Then, the effects of the combination impeller on the flow characteristics of the impeller and volute are clarified by comparing simulation results with that of the conventional impeller, where the effectiveness of the selected numerical method is validated by an acceptable agreement between simulation and experiment. Finally, the experiment is set to test the external performance of the studied pump. A significant feature of this study is that the flow characteristics are significantly ameliorated by reducing the flow losses that emerged in the impeller inlet, impeller outlet, and volute tongue. Correspondingly, the head and efficiency of a combination impeller are higher with comparison to a conventional impeller. Consequently, it is a promising approach in ameliorating the flow field and improving external performance by applying a combination impeller to an aero-fuel centrifugal pump.

PS&S undertook the evaluation of an existing 100,000-gallon elevated water storage tank (located at the Borough’s Union Lane DPW yard) which was experiencing low water turnover, diminished HGL levels, and structural deficiencies.
As part of a holistic approach, PS&S was authorized to evaluate water movement throughout the Borough’s entire water distribution network via WaterCAD modeling in order to determine optimal tower water levels in both of the Borough’s existing tanks, and to evaluate the feasibility of eliminating or replacing the Union Lane Elevated Tank.
THE PS&S SOLUTION
PS&S analyzed the water age, water movement between two separate pressure zones, and chlorine residual levels. Solutions included the addition of new, pressure reducing valve (PRV) pits at optimum points on the pressure zone boundaries, new transmission mains at critical junctions, and replacement of the existing tank with a lower HGL tank. Ultimately, a decision was made to design a new 300,000-gallon elevated tank, which will provide higher operating pressures and a more reliable water storage source for Brielle residents and businesses. Project funding was secured via a NJEIT low-interest loan.

Phidim, April 21
Although construction of Kabeli B1 hydropower project is on its last leg, power generated by the project is likely to be connected to the national grid due delay in laying of the transmission line.
Earlier, the project had stated that it would start generating power by mid-May. The 25MW capacity power project is based on the Kabeli Khola river flowing between Taplejung and Panchthar districts. As per sources, the delay in the completion of the project has to do with the tardy construction of the Kabeli corridor that is being carried out by Nepal Electricity Authority.
Chief technician Hastaman Rai at Arun Kabeli Power Limited, the developer of the project, said construction of the project was likely to take some more time. “We’ve completed work related to surge tank, powerhouse and the likes and even the installation of penstock pipe is on the last leg. But as the transmission line is not ready, the power generated by the project is likely go to waste causing loss.” Earlier, NEA Executive Director Kulman Ghising had monitored the progress on the transmission line project.

The Zurn Wilkins Model ZW205 Pilot Operated Pressure Relief/ Pressure Sustaining Valve is designed for applications where it is critical to maintain a pre-determined upstream pressure. The pilot assembly reacts to changes in upstream pressure allowing the main valve to modulate between the closed and open position, maintaining desired upstream set pressure. As long as the upstream pressure is below the set point of the pilot assembly, the main valve will stay in the closed position (sustaining); however, once the upstream pressure exceeds the set point of the pilot assembly, the main valve will open and relieve the excess pressure (relief).
