Mass Transfer In a packed tower, the value of HETP equals HTUOG, when the equilibrium and the operating lines are (where, HETP = height equivalant to a theoretical plate HTUOG = overall gas phase height of a transfer unit) Neither A nor B Both A & B Straight Parallel Neither A nor B Both A & B Straight Parallel ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The cooling effect in a cooling tower can not be increased by Increasing the air velocity over the wet surfaces Reducing the humidity of entering air None of these Lowering the barometric pressure Increasing the air velocity over the wet surfaces Reducing the humidity of entering air None of these Lowering the barometric pressure ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The reason for preferring packed towers over plate towers in distillation practice is that the packed tower operation gives High pressure drop and low hold up Low pressure drop and low hold up High pressure drop and high hold up Low pressure drop and high hold up High pressure drop and low hold up Low pressure drop and low hold up High pressure drop and high hold up Low pressure drop and high hold up ANSWER DOWNLOAD EXAMIANS APP
