Q$2$

Water is required to transferred from a lower tank to a higher tank by a pump. The details of the flow system are given in the figure. The head loss coefficients for the entrance, bend and exit are $0\mathrm{.}5,0\mathrm{.}35$ and $1\mathrm{.}0.$

Elevation $=230m$

The pump curve is given in the right figure. If the pump has an efficiency of $75\%,$ determine pump flow rate and the needed shaft power.
