2. An air sample, having 45°C dry bulb temperature and 20% relative humidity, is humidified to 80% relative humidity in an adibatic humidification chamber. Then the air is cooled to 20°C after the humidification process. (30 P) a) Find the amount of liquid water (kg/s) evaporated into air in the humidification chamber for 5 m3/s of inlet air. b) Find the humidity ratio and relative humidity of the air after cooling process.
