A Rotary drum fiter with 30% Submengance is to be used to filter a concentrated aqueous slurry of calcium carbonate contuning 15lb solid/ ft3 of water. The pressure drop is 1500 water. 1bff/ft2. If fiter cake contains 50% moisture. Calculate total fiter area. requined to Produce 0.4lb/s of solids. The fiter crole time is 4min. Assume a=2.91010(p)0.26ftc/16, whene is in 1bf/ft2. Assume Rm is negligible The viscosity of water is 6.72104Hb/b/(fts) Density of water =62.3lb/ft3. Calculate value of gc=32.2kb. ftt /1bf.s2 Write your answer with corrrect unit. write down the steps used in calculations (6Mank)
