Mass Transfer Air initially at 101. 3 kPa and 40°C and with a relative humidity of 50%, is cooled at constant pressure to 30°C. The cooled air has a Higher wet bulb temperature Higher relative humidity Higher absolute (specific) humidity Higher dew point Higher wet bulb temperature Higher relative humidity Higher absolute (specific) humidity Higher dew point 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
