A rapid sand filter has a sand bed 760mm in depth. Pertinent data are: specific gravity of the sand = 2.65, shape factor (ᴓ) = 0.75, porosity (ԑ) = 0.41, filtration rate = 1.53 liter /s-m2, and operating temperature = 10°C. The sieve analysis of the sand is given in the following table. Determine the head loss for the clean filter bed (in m) in a stratified condition Sieve Size Weight retained % 14-20 0.44 20-28 14.33 28-32 43.22 32-35 27.07 35-42 9.76 42-48 4.22 48-60 0.54 60-65 0.29 65-100 0.13
