Outside air at 10 degC, 1 bar and 40% relative humidity enters an air conditioner operating at steady state with a mass flow rate of 1.5kg/s. The air is first heated at essentially constant pressure to 30 degC. Liquid water at 15 degC is then injected, bringing the air to 25 degC, 1bar.

Determine

(a) the rate of heat transfer to the air passing through the heating section, in kJ/s.

(b) the rate of water is injected, in kg/s.

(c) the relative humidity at the exit of the humidification section.

Kinetic and potential energy can be ignored.
