A small, pumped storage scheme is used to pump water to a reservoir during the night and to generate power during peak demand times in the late afternoon. The pumped storage scheme consists of a pump and an impulse turbine as shown in the figure below. 4.1 The reservoir is initially to be filled with the pump which can deliver a constant head of 36 m water.

Question
A small, pumped storage scheme is used to pump water to a reservoir during
the night and to generate power during peak demand times in the late
afternoon. The pumped storage scheme consists of a pump and an impulse
turbine as shown in the figure below.
4.1 The reservoir is initially to be filled with the pump which can deliver a
constant head of 36 m water. Determine the time it will take to fill the
reservoir.
4.2 The reservoir is to be drained for maintenance purposes by disconnecting
it from the pump and turbine. Calculate the time that it will take to drain
the reservoir.
4.3 Calculate the flowrate at the pipe outlet to the impulse turbine when the
water level in the reservoir is kept constant.
4.4 Calculate the head loss against friction and the hydraulic power available
for case 1.3 above.
