Topic: Filtration

Determine the clean water head loss $($using 'Rose Equation'$)$ in a filter bed composed of $1\mathrm{.}2m$ of uniform sand with the distribution given below for a filtration rate of $0\mathrm{.}22\frac{m^3}{m^2}-$min. The operating temperature is $25C.$ Assume the shape factor for the sand is $0\mathrm{.}7,$ and the porosity of the sand in different layers is $0\mathrm{.}45.$ At $25C,v=1\mathrm{.}0034**{10}^{-6}\frac{m^2}{s}$
