Can someone solve this please? ENVE 4410/5510 INTRODUCTION TO ENVIRONMENTAL ENGINEERING PROBLEM SET NO. 9 Filtration 1. (VH, p.348,10.28) Using the Kozeny equation, calculate the initial head loss (in ft) through a filter with 18 in. of uniform sand having a porosity of 0.42 and a grain diameter of 1.6 x 103 ft. Assume spherical particles and a water temperature of 50°F. The filtration rate is 2.5 gpm/ft 2. (DC, p 280; 3-81) The rapid sand filter being designed for...
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 L/m^2*s, and the water temperature is 10 C. The filter depth is 0.7 m with a porosity of 0.45, and the sand grains have a sphericity of 0.75. Sieve designation number 12 16 20 30 40 50 Fraction of sand retained 0 0.05 0.22 0.51 0.20 0.02 Determine the effective size and uniformity coefficient for the...
