In reference to problem number 1, if another pump was used having a power requirement of 12 hP with an efficiency of 73% in pumping the water at 1.2 ft3 /s through a constant diameter of a pipe. Determine the irreversible head loss of the piping system in ft of water if the free surface of the pool was at 35 ft?
kindly answer only number 5 1 is just a reference
1. A water from Agno River is pumped 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. If the power
requirement of the pump is 5 kW assuming that the elevation difference between the pump inlet and outlet
and the effect of the kinetic energy correction factors 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 ₱2.00/kW-h
5. In reference to problem number 1, if another pump was used having a power requirement of 12 hP with an
efficiency of 73% in pumping the water at 1.2 ft3
/s through a constant diameter of a pipe. Determine the
irreversible head loss of the piping system in ft of water if the free surface of the pool was at 35 ft?
