2. [30 Pts] Water is pumped at 1500 m/min from the lower to the upper reservoir. Pipe friction head loss is approximated by h = 27V/(2g), where V is the average velocity in the pipe. If the pump is 75% efficient, what power is needed to drive it? Gravitational acceleration g = 9.8 m/s. PH0 = 1000 kg/m = Z2 = 150 m Z = 50m D = 6m Pump
