Question: An air-conditioning system operates at a total pressure of 1 atm and consists of a heating section and an evaporative cooler. Air enters the heating

An air-conditioning system operates at a total pressure of 1 atm and consists of a heating section and an evaporative cooler. Air enters the heating section at 10°C and 70 percent relative humidity at a rate of 30 m3/min and it leaves the evaporative cooler at 20°C and 60 percent relatively humidity. Determine
(a) The temperature and relative humidity of the air when it leaves the heating section,
(b) The rate of heat transfer in the heating section, and
(c) The rate of water added to air in the evaporative cooler.
