Air at 30°C Dry-bulb temperature, 40% RH enters a heating chamber at the rate of 500 cmh (cu.m/hr). The air undergoes constant temperature heating and leaves the chamber with an RH of 70%. (a.) At standard atmospheric condition, find the heat added (in kW) and the amount water added (in kg/min). (b.) Solve part (a) if the total pressure of the air is 80 kPaa.
