Mass Transfer As the reflux ratio increases, the slope of the operating line for rectifying section Increases Data insufficient, cannot be predicted Decreases Remains constant Increases Data insufficient, cannot be predicted Decreases Remains constant ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer As the reflux ratio in a distillation coloumn is increased from the minimum, the Liquid flow increases while the vapor flow decreases for a system Total cost first decreases and then increases Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly Liquid flow increases while the vapor flow decreases for a system Total cost first decreases and then increases Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Cox chart, which is useful in the design of distillation column particularly for petroleum hydrocarbons, is a plot of (where, P = vapor pressure, T = temperature) T vs .
