The uniformity coefficients are 1.5 for each of the media. Perform all calculations for a temperature of 10 o C. Divide each medium into three layers on a weight basis. (a) Calculate the mintial headloss through the bed if the loading rate is 200m 3 /m 2 / d. Given: ρ = 999.7 kg/m 3 , μ=1.307 x 103 N·s/m 2...
