A bag house having 20 compartments, 360 bags per compartment, and each bag with a diameter of 11 m and a length of 30 m is used to treat 1,200,000 m/min of polluted air carrying dust particles (specific gravity of 2.0) at a concentration of 1.5 g/m. The collection efficiency is 99%, and the bags are cleaned every hour. Assuming that 2 compartments are cleaned simultaneously at a time, and the cake is 50% voids, determine the following: i. The gross and net air-to-cloth ratios ii. The cake thickness
