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...

Q2. 50 marks Water at 20°C is pumped at 5.7 m3 min-1 from the lower to the upper reservoir, as in Fig. 2. The free surface of the upper reservoir is at height Z2 = 46 m, and of the lower reservoir at 21 = 15 m. The pipe diameter before and after the pump is D= 15 cm. Pipe friction losses are approximated by h = 27v2/(29), where V is the average velocity in the pipe. The gravitational acceleration...
