Question $4$: A bar screen is inclined at a $\backslash (45^\{\backslash$circ$\}\backslash )$ angle from the horizontal. Determine the head loss through a bar screen when it is $\backslash (50\backslash \%\backslash )$ clogged. The wastewater flows through the screen at a rate of $\backslash (0\mathrm{.}23\backslash$mathrm$\{$~m$\}^\{3\}/\backslash$mathrm$\{$s$\}\backslash ).$ The screen consists of $25$ bars given that the width of the bars is $2$ cm $,$ the space between two bars is $5$ cm and the channel height is $30$ cm $.$ The overall submerged area of the screen is $\backslash (0\mathrm{.}6\backslash$mathrm$\{$~m$\}^\{2\}\backslash ).$ Consider flow coefficient for clogged bar rack as $0\mathrm{.}6.$

Answers: $0\mathrm{.}093$ m
