Mass Transfer The cooling effect in a cooling tower can not be increased by Reducing the humidity of entering air Lowering the barometric pressure Increasing the air velocity over the wet surfaces None of these Reducing the humidity of entering air Lowering the barometric pressure Increasing the air velocity over the wet surfaces None of these ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer At equilibrium the concentration of water in vapour phase (C*)in kg/m³ of air space and the amount of water (m) adsorbed per kg of dry silica gel are related by, C* = 0.0667m. To maintain dry conditions in a room of air space 100m³ containing 2.2 kg of water vapour initially, 10 kg of dry silica gel is kept in the room. The fraction of initial water remaining in the air space after a long time (during which the temperature is maintained constant) is 0.2 0.4 1 0.2 0.4 1 ANSWER DOWNLOAD EXAMIANS APP
