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 0.4 0.2 1 0.4 0.2 ANSWER DOWNLOAD EXAMIANS APP
