Mass Transfer As the reflux ratio in a distillation coloumn is increased from the minimum, the Number of plates decreases very slowly first and then more and more rapidly Slope of the operating line in stripping section decreases Liquid flow increases while the vapor flow decreases for a system Total cost first decreases and then increases Number of plates decreases very slowly first and then more and more rapidly Slope of the operating line in stripping section decreases Liquid flow increases while the vapor flow decreases for a system Total cost first decreases and then increases ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer When an unsaturated air-water mixture is heated at constant pressure, then The specific humidity decreases The partial pressure of water vapour increases The relative humidity increases The relative humidity decreases The specific humidity decreases The partial pressure of water vapour increases The relative humidity increases The relative humidity decreases ANSWER DOWNLOAD EXAMIANS APP
