In a hydroelectric power station, the turbine is driven by water flowing from a reservoir at the rate of 551 m s. The water is pumped through a pipe 2.06 km long of 2.53 m intemal diameter with a friction factor of 0.004. The water is assumed to have a kinematic viscosity of 13x10 mʻls. The elevation of the upper reservoir above sea level is 400 m and that of the lower reservoir is 40 m. Determine the following Mean...

A hydro power station uses Pelton turbine to generate power from a water body behind a dam which has the height of 40 m. (a) Estimate the maximum jet speed to be used to drive the Pelton turbine. (b) The height of the dam water remain constant as a results of a river, with flow rate of 500 m3 s −1 , flowing into the dam reservoir. Estimate the power generating capacity of this river-dam configuration

A 60 horsepower pump is used to move water from a large reservoir to another at a higher elevation. Measured data show that the head loss from station 1 to 2 can be calculated from hloss= cV2 where V is the fluid velocity in the pipeline and c is a constant Calculate the volumetric flow rate, Q, if c=2 s2/ft, d=10 in., h=50 ft , and npump=0.85 h Pump

1. You are designing a pumping station and have been asked to size and select a pump from 2 models. The system step is as follows: the discharge line is a 21-inch diameter PVC pipe with an assumed constant friction factor of f 0.014. The length of the piping is 2300 ft with an elevation gain of 40 ft and an exit loss (K-1.0).. The pump station is located near sea level and the temperature of the flow stream is...

A. 2 pts. Consider a small hydroelectric power station that generates 1000 kW of electrical power. Water passes through the turbine as it falls from the reservoir level down a vertical drop of 25.0 m to the river below the dam. Assuming 80.0% conversion efficiency, what volume of water must pass through the turbine each second? (give answer in m') p= density of water 1000 kg/m3 g=9.81 ms-2 B. 2 pts. Determine the total energy content of all the natural...
