Calculate the clean$-$bed head loss through a deep$-$bed anthracite filter with $1\mathrm{.}8$m of ES $=0\mathrm{.}95$ mm media at a filtration rate of $15$ m$/$h and a temperature of $15$ C$.$ Use the Ergun equation. Assume the following parameters apply: kv $=228,$ ki $=4\mathrm{.}4,\backslash$epsi $=0\mathrm{.}50,\backslash$rho $=999$ kg$/$m$3,\backslash$mu $=1\mathrm{.}14$ x $10-3$ kg$/$m$-$s$.$
