A bar screen is used to remove the coarse suspended solids from influent wastewater. The design flowrate for the WWTP is $27648\frac{m^3}{d}.$ Approach velocity in the screen channel $(v_{\text{a}\text{p}\text{p}})$ is $0\mathrm{.}3\frac{m}{s}$ and flow$-$through velocity of the clean screen $(V_{scr})$ is $0\mathrm{.}75\frac{m}{s}.$ The water depth in approach channel is $0\mathrm{.}5m$ and the cross$-$sectional width of each bar is $0\mathrm{.}010m.$ Find the number of bars in this coarse screen?ANSWER $$S $128$ PLEASE BE CAREFULL!!!
