A water from Agno River is pumped at 13.3 L/s using a submerged pump at an efficiency of 78% that is discharged to a swimming pool in Itogon which has a free surface of 30 m above the Agno River water level. The pipe that was used has a diameter of 7 cm on the suction line and 5 cm on the discharge line from the pump. Assuming that the elevation difference between the pump inlet and outlet and the effect of the kinetic energy correction factors and frictional losses in piping are negligible, calculate for the following a) Power requirement by the pump in kW b) Pressure difference across the pump c) Pumping cost/day(24 hour) if the electricity cost is P2.00/kW-hr
