A rotary drum filter with 35% submergence is to be used to filter a concentrated aqueous slurry of calcium carbonate containing 12 lb solid/ft of water. The pressure drop is 1400 lb/ft2. If filter cake contains 50% moisture, calculate total filter area required to produce 0.3 lb/s of solids. The filter cycle time is 6 min. Assume a = 2.9 x 100 (AP) 0.26 ft/lb, where AP is in lb/ft2. Assume Rm is negligible. The viscosity of water is 6.72 x 10-4 lb/(ft.s). Density of water = 62.3 lb/ft Consider value of go 32.2 lb.ft/lb.s. Write your answer with correct units. Write down the steps used in calculations, wherever possible. [6M]
