2. A sanitation district is to install rapid sand filters downstream of the clarifiers. The design- loading rate is selected at 190 m/m per day. The design capacity of the waterworks is 0.30 m/sec. The maximum surface per filter is limited to 50 m² • a.) Design the number and size of filters (Assume the cross section of filters is square, determine the length of side); calculate the normal filtration rate base on your design. b.) A sieve analysis curve...

Subject: Geotechnical Engineering (soil mechanics). Q3. A sand sample of 35 cm2 cross sectional area and 20 cm long was tested in a constant head permeameter. Under a head of 60 cm, the discharge was 120 ml in 6 min. The dry weight of sand used for the test was 1120 gm, and Gs = 2.68. Determine (a) the hydraulic conductivity in cm/sec, (b) the discharge velocity, and (c) the seepage velocity.
