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 0.4 0.2 1 0.4 0.2 1 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Henry's law states that the Partial pressure is equal to the product of the mole fraction and total pressure Partial pressure of a component over a solution is proportional to the mole fraction in the vapour Partial pressure of a component over a solution is proportional to its mole fraction in the liquid Vapour pressure is equal to the product of the mole fraction and total pressure Partial pressure is equal to the product of the mole fraction and total pressure Partial pressure of a component over a solution is proportional to the mole fraction in the vapour Partial pressure of a component over a solution is proportional to its mole fraction in the liquid Vapour pressure is equal to the product of the mole fraction and total pressure ANSWER DOWNLOAD EXAMIANS APP
