$7\mathrm{.}44$ Water $(10C)$ is flowing at a rate of $0\mathrm{.}35\frac{m^3}{s},$ and it is assumed that $h_L=2\frac{V^2}{2}g$ from the reservoir to the gage, where $V$ is the velocity in the $30cm$ pipe. What power must the pump

Problem $7\mathrm{.}44$

For Problem $7\mathrm{.}44,$ if the pump runs $2$ hours per day, the pump efficiency is $83\%$ and the motor efficiency is $97\%,$ and the cost to purchase electricity is $$\frac{0\mathrm{.}15}{K}WH,$ what is the minimum motor output power and the monthly cost to run the pump.
