Question $1$: Compulsors $(30\%)$

The water surface elevation in the lower reservoir $($A$)$ is $60m($above the pump level$),$ and the surface elevation in the upper reservoir $($B$)$ is $80m($above the pump level$).$ All the information about the pipes characteristicn are given in Table below. Assume the pump efficiency is $90\%$

a$)$ What power is required to pump water at a rate of $0\mathrm{.}10\frac{m^3}{s}$ from the lower to the upper reservoir?

b$)$ Calculate the pressure at the pump inlet.

c$)$ Calculate the pressure at the pump outlet.

d$)$ Sketch the HGL and the EGL including the friction losses and minor losses.

Assume $=1\mathrm{.}0$ at all locations and the pipe friction loss is given by $ht-f(\frac{L}{D})(\frac{V^2}{2}(g)),$ where $L.$ is the length of pipe, $D$ is the pipe diameter, $f$ is the friction coefficient and $V$ is the velocity in the pipe? Minor loss coefficients $($k$)$ are given as below.

NOTE: Draw EGL and HGL on the next sheet provided.
