**Problem Statement:**The machine in the following figure acts as a turbine during daytime to produce electricity and as a pump during nighttime to move water back to the reservoir with higher elevation. For a design flowrate of 33 ft³/s in either direction, the headloss is 17 ft. Estimate power (\( W = \gamma Q h_s \)):(a) extracted by the machine as a turbine;(b) delivered by the pump.**Diagram Explanation:**The diagram illustrates a system consisting of two reservoirs at different elevations. The higher reservoir is at an elevation \( Z_1 = 150 \) ft above the datum, and the lower reservoir is at \( Z_2 = 75 \) ft. 1. **Water Flow as a Turbine:** - During the daytime, water flows from the higher reservoir to the lower reservoir through a machine acting as a turbine, generating electricity. 2. **Water Flow as a Pump:** - At nighttime, the machine operates as a pump. It moves water from the lower reservoir back to the higher reservoir, working against gravity.3. **Headloss:** - The system experiences a headloss of 17 ft in both directions due to friction and other factors within the pipes and equipment.This setup is an example of a pumped-storage hydroelectric system, which balances electricity demand and supply by storing energy at times of low demand and releasing it at times of high demand.

A hydro-electric power plant consumes 52,659,000 KW-hrs per annum. Expected flow is 1665 cu. m/ min and overall efficiency is 65%. What is the net head?
(a) Water flows by gravity from one lake to another as illus- trated; the surface levels of the lakes differ by an eleva- tion of h= 50 ft. If the volumetric flow rate is steady at Q = 80 gallons per minute, what is the associated loss of available energy? (b) A pump is to be installed to pump the water from the lower lake to the upper lake with the same flow rate as above (Q = 80 gpm). If the amount of energy loss is assumed to be the same as in part (a), how much mechanical power must be supplied by the pump? Answer: (a) loss = 1600 ft-lb/slug, (b) Wpump = 2.0 hp
