An air sample, having 45°C dry bulb temperature and20% relative humidity, is humidified to 80% relative humidity in anadibatic humidification chamber. Then the air is cooled to 20°Cafter the humidification process.
a) Find the amount of liquid water (kg/s) evaporated into air inthe humidification chamber for 5 m3/s of inlet air.
b) Find the humidity ratio and relative humidity of the air aftercooling process.
