How to solve

$2\mathrm{.}10-9.$ Friction Loss in Pumping Oil to Pressurized Tank. An oil having a density of $833k\frac{g}{m^3}$ and a viscosity of $3\mathrm{.}3{10}^{-3}Pa*s$ 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 through a line of commercial steel pipe having an inside diameter of $0\mathrm{.}07792$ m at the rate of $3\mathrm{.}494{10}^{-3}\frac{m^3}{s}.$ 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 $65\%.$ Calculate the kW power of the pump. $,{\displaystyle \underset{?}{\overset{?}{}}}hf=15\frac{J}{k}g$;$P=1\mathrm{.}04kW$
