Which of these is incorrect for a band-stop filter? Correct Answer The LPF and HPF are connected in series

When designing a band-stop filter, a HPF and LPF are connected in parallel, and their output goes into the input of an adder to get the desired output. For correct output, the cut-off frequency of HPF should be much higher than that of the LPF.

A rotary drum filter with 30% submergence is used to filter concentrated aqueous slurry of calcium carbonate containing 15lb of solids per cubic foot of water. The pressure–drop is 2011Hg. If the filter cake contains 50% mixture (wet basis), calculate the filter area required to filter 10 gal/min of slurry. The filter cycle time is 5 min. The specific cake resistance depends on the pressure–drop as: α (ft/lb) = α (Δp)0.26, where α = 2.90×1010 Viscosity of the filtrate = 6.72×10-4 lb/ft-s. Density of calcium carbonate = 168.8 lb/ft3. Neglect filter medium resistance.
