Mass Transfer A 25 cm x 25 cm x 1 cm flat sheet weighing 1.2 kg initially was dried from both sides under constant drying rate conditions. It took 1500 seconds for the weight of the sheet to reduce to 1.05 kg. Another 1m x 1m x 1cm flat sheet of the same material is to be dried from one side only.Under the same constant drying rate conditions, the time required for drying (in seconds) from its initial weight of 19.2 kg to 17.6 kg is 1500 2500 1000 2000 1500 2500 1000 2000 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 Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system Number of plates decreases very slowly first and then more and more rapidly Slope of the operating line in stripping section decreases Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer According to the Fenske equation, what will be the minimum number of plates required in a distillation column to separate an equimolar binary mixture of components A and B into an overhead fraction containing 99 mol% A and a bottom fraction containing 98 mol% B? Assume that relative volatility (αAB = 2) does not change appreciably in the coloumn. 12 10 6 8 12 10 6 8 ANSWER DOWNLOAD EXAMIANS APP
