b) Energy may be stored for use during peak demand by pumping water to a high reserveir when needed. Suppose water is pumped to a lake 135 m above the turbines and at a rate of 1.35 x 10 kgs" for 10 hrs at night. i) How much energy (kWh) is needed to do this each night. ii) If all this energy is released during a-14 h day, at 75% efficiency, wvhat is the average power output?
