Eight rapid-sand filters treat a total of 1.2 m/s of water. Each filter bed has approximately 90 percent and 10 percent of 20-40 US mesh and 40-70 US mesh sand grains, respectively. The filter bed has a depth of 0.65 m, a porosity of 0.42, and a grain shape factor of 0.9. The absolute viscosity and the density of water are 1.139 x 10-3 Pa-s and 999 kg/m², respectively. At a filter loading rate of 190 m²/d-m?, determine: (a) the head loss for clean filters using the Rose equation. (b) the size and dimensions of square filters.
