Mass Transfer The velocity, concentration and temperature boundary, for the boundary layer development on a flat plate during connective mass transfer will be same, if NSc = NPr = NLe NPr = NLe NSc = NLe NSc = 1 NSc = NPr = NLe NPr = NLe NSc = NLe NSc = 1 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 0.4 1 0.2 0.4 1 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In a distillation operation, what is the effect of the temperature of the reflux stream (given below) on the condenser and reboiler loads? Reflux conditions:(i) Reflux stream is completely liquid and is at its bubble point.(ii) Reflux stream is below its bubble point. Reboiler load is the same in both the cases but condenser load is higher in case (ii) Condenser load is the same in both the cases but reboiler load is higher in case (ii) Condenser and reboiler loads are the same in both the cases Both condensor and reboiler loads are higher in case (ii) as compared to case (i) Reboiler load is the same in both the cases but condenser load is higher in case (ii) Condenser load is the same in both the cases but reboiler load is higher in case (ii) Condenser and reboiler loads are the same in both the cases Both condensor and reboiler loads are higher in case (ii) as compared to case (i) ANSWER DOWNLOAD EXAMIANS APP
