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

Dry bulb temperature of unsaturated air is more than its __________ temperature.

For the case of flow of air past a wet bulb thermometer (air water vapour system), the approximate value of h₂/k_y.C_z is around

The reciprocal of stripping factor is termed as

Ponchan-Savarit method analyses the fractional equipment based on
