An oil having a density of 833 kg/m3, and a viscosity of 3.3x10^-3 Pa-s is pumped from an open tank to a pressurized tank held at 345 kPa gage. The oil is pumped from an inlet at the side of the open tank though a line of commercial steel pipe having an inside diameter of 0.07792 m at a rate of 3,494x10^-3 m3/s. The length of straight pipe is 122 m, and the pipe contains two elbows (90°) and a globe valve half open. The level of the liquid in the open tank is 20 m above the liquid level in the pressurized tank. The pump efficiency is 75%. Calculate the kW power of the pump.

Question
An oil having a density of 833 kg/m3, and a viscosity of 3.3x10^-3 Pa-s is pumped
from an open tank to a pressurized tank held at 345 kPa gage. The oil is
pumped from an inlet at the side of the open tank though a line of
commercial steel pipe having an inside diameter of 0.07792 m at a rate of
3,494x10^-3 m3/s. The length of straight pipe is 122 m, and the pipe contains
two elbows (90°) and a globe valve half open. The level of the liquid in the
open tank is 20 m above the liquid level in the pressurized tank. The pump
efficiency is 75%. Calculate the kW power of the pump.
