Mass Transfer In liquid extraction, if the selectivity is unity, then Separation of the constituents is the most effective Amount of solvent required will be minimum No separation will occur Solvent flow rate should be very low Separation of the constituents is the most effective Amount of solvent required will be minimum No separation will occur Solvent flow rate should be very low ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The drying time between fixed moisture content within diffusion controlled 'falling rate period' is proportional to (assuming that drying occurs from all surfaces of the solid) (where, T = thickness of the solid ) T T² √T T³ T T² √T T³ ANSWER DOWNLOAD EXAMIANS APP
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
