Mass Transfer Acetone is to be removed from air in an isothermal dilute absorber using pure water as solvent. The incoming air contains 5 mole% of acetone (yin = 0.05). The design equation to be used for obtaining the number of trays (N) of the absorber is, N+2 = 6 log (yin/yout).For 98% recovery of acetone, the number of trays required is/are 8 10 1 9 8 10 1 9 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 0.2 1 0.4 0.2 1 0.4 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In an operating distillation column, the Driving force for the liquid flow is its specific weight Vapors and liquids are at their dew point and bubble point respectively Highest temperature is encountered at the top of the column Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Driving force for the liquid flow is its specific weight Vapors and liquids are at their dew point and bubble point respectively Highest temperature is encountered at the top of the column Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column ANSWER DOWNLOAD EXAMIANS APP
