Moist air at 10°C, 101.325 kPa, and a relative humidity of 40% enters a heating and humidifying system at a volumetric flow rate of 2.0 m³
/s. The air is to be humidified using liquid water, and the final exit state of the air is to be 25°C and 40% relative humidity. Plot the rate of heat addition, the temperature of the air between the heating and humidification systems, and the amount of water needed to be added as the temperature of the liquid water varies between 10°C and 50°C.
