3. In a small hydroelectric power station, the turbine uses the energy of the water in the reservoir behind the dam to produce 12000 horsepower. The circular channels before and after the turbine have a diameter of 90 inches. If the head loss across the dam can be calculated from hloss=cV²/2g where c=8 and V is the water velocity in the circular channel, calculate the volumetric flow rate, Q, through the system and the corresponding head loss for h=400 ft...

A pumped-storage hydroelectric plant generates high value electricity during peak demand times, by allowing water (density 1,000 kg/m3) to run through a pipe from an elevated reservoir through a bank of turbines and then into a lower level reservoir. It then uses low-cost, off-peak electricity to pump the water back up into the upper reservoir The water surface in the very large upper reservoir (A) is 600 m above datum whilst that in the very large lower reservoir (B) is...

A micro hydro turbine is used to generate hydroelectric power by letting liquid water from a high elevation run through the turbine to a low elevation. The turbine is under a steady state operation condition. The inlet water and outlet water are at elevations of 10 m and 2 m, respectively. The inlet and outlet diameters are 0.3 m and 0.5 m, respectively. The inlet pressure is 2.5 bar and the outlet pressure 1 bar. The inlet and outlet temperatures...

Q4: The pump is used to deliver of water from a river to a storage reservoir. The four pipes are connected in series of Inverse L shape which means the first pipe in vertical direction and others in horizontal direction. The first pipe in vertical position of 500m length of 150 mm diameter cast iron pipe, the second pipe is bend at 90' with a radius of 0.75m, the third pipe in horizontal direction of 100m length of 160mm diameter...

The vertical drop of water in a hydroelectric power plant is 155m (See figure below). Water flows through the plant and into the lower river at the rate of 425m/s. Assume the overall efficiency of the plant as 80%. Density of water d is equal to 1000kg/m3 Acceleration due to gravity g is equal to 9.81m/s2. Ignore the viscous losses in the flowing water.
