![| 1. 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
