Calculate the head loss through a clean sand filter with a gradation as given by the sieve analysis below. The filtration rate is 2.7 1/m2 s, and the water temperature is 10° C. The filter depth is 0.70 m with a porosity of 0.45, and the sand grains have a sphericity of 0.75.
Sieve esignation number | 12 | 16 | 20 | 30 | 40 | 50 |
Fraction of sand retained | 0 | 0.05 | 0.22 | 0.51 | 0.20 | 0.02 |
