A pump draws water from a large open sump through a short length of the suction pipe. The water is delivered through a 21.1 m length of 9 cm diameter pipe and via a submerged exit into an open tank. A control valve is installed in the delivery pipe, for which f = 0.0085. Dissipation other than friction and the loss at the valve may be ignored. The bottom of the tank is 10 m above the free surface of the water in the sump. What power will be required in kW if the water will be delivered to 1.5m above the pump?
