Mass Transfer In continuous distillation, the internal reflux ratio (Ri) and the external reflux ratio (Re) are related as Ri = Re/(1 - Re) Ri = (1 - Re)/Re Ri = Re Ri = Re/(1 + Re) Ri = Re/(1 - Re) Ri = (1 - Re)/Re Ri = Re Ri = Re/(1 + Re) ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer At equilibrium the concentration of water in vapour phase (C*)in kg/m³ of air space and the amount of water (m) adsorbed per kg of dry silica gel are related by, C* = 0.0667m. To maintain dry conditions in a room of air space 100m³ containing 2.2 kg of water vapour initially, 10 kg of dry silica gel is kept in the room. The fraction of initial water remaining in the air space after a long time (during which the temperature is maintained constant) is 1 0.2 0.4 1 0.2 0.4 ANSWER DOWNLOAD EXAMIANS APP
