Question $5$: Design and Head Loss Calculations for Bar Screen in Water

Treatment $(3$ marks$)$

A water treatment plant receives a flow of $24,000\frac{m^3}{?}$ day.

A bar screen is used to remove the coarse waste. The velocity in the approach channel $($v$)$ is $0\mathrm{.}5\frac{m}{s}$ and the flow$-$through velocity of the clean screen $($V$)$ is $0\mathrm{.}8\frac{m}{s}.$ Calculate the required open screen area to achieve this screen velocity during treatment of the rainwater flow.

Calculate the head loss of this clean screen using the friction coefficient $C=0\mathrm{.}7.$
