An air conditioning system operates at a total pressure of 1 atm consists of a heating section and humidifier which supplies wet steam (saturated water vapor) at 1 atm. Air enters the heating section at 15oC and 75% relative humidity at 60m3/min, and it leaves the humidifying section at 24oC and 55% relative humidity . Determine
The temperature and
Relative humidity of air when it leaves the heat section,
Rate of heat transfer in the heating section and
The rate at which water is added to the air in the humidifying section.
