Question:

Water at 25oC is being pumped at 1.5 kg/s from an open reservoir through a 10-cm pipe. The open end of the 5-cm discharge pipe is 15 m above the top of the water surface in the reservoir.
Neglecting any losses, determine the power required in kW. Assume the temperature to remain unchanged and use the SL model for water.
