Water is pumped from a 200 m (deep) well into a 200 m (tall) water storage tank.
a) Determine the power (in kW) that is required to pump at a rate of 400 L/min.
b) Determine the total power (in kW) that is required to pump 1000 L/min if the pump is 60% efficient and is driven by a 90% efficient motor.
