The water is to be pumped from the lower reservoir to the upper reservoir at a flow rate of 8 kg/s. The free surface of the upper reservoir is 254 meters above the free surface of the lower reservoir. The piping system shown has a pipe diameter of 8 cm and a total frictional loss (major and minor) of 27 meters. The pipe entrance is 4 meters below the free surface of the lower reservoir and the pipe exit is 2 meters below the free surface of the upper reservoir. Determine the power required to pump the water if the pump is 85% efficient. Use the water density as 998 kg/m3.

Question
The water is to be pumped from the lower reservoir to the upper reservoir at a flow rate of 8 kg/s. The free surface of the upper reservoir is 254
meters above the free surface of the lower reservoir. The piping system shown has a pipe diameter of 8 cm and a total frictional loss (major and
minor) of 27 meters. The pipe entrance is 4 meters below the free surface of the lower reservoir and the pipe exit is 2 meters below the free
surface of the upper reservoir. Determine the power required to pump the water if the pump is 85% efficient.
Use the water density as 998 kg/m3.
