Bag filter design is predominantly dependent on gas temperature, as it affects the gas density & viscosity and the selection of filtering material. The pressure drop in a bag filter is
Options
A. inversely proportional to viscosity of gas.
B. proportional to the viscosity & density of the gas.
C. proportional to the pressure of the gas.
D. both (b) and (c).
