Estimate the clean$-$bed head loss through a filter with a $2\mathrm{.}0$ m depth of processed sand $($effective size of $0\mathrm{.}75$ mm and uniformity coefficient of $1\mathrm{.}5)$ at a filtration rate of $\backslash (12\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$h$\}\backslash )$ and a temperature of $\backslash (25^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$
