Outside air at 10 degC, 1 bar and 40% relative humidity entersan air conditioner operating at steady state with a mass flow rateof 1.5kg/s. The air is first heated at essentially constantpressure 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 theheating section, in kJ/s.
(b) the rate of water is injected, in kg/s.
(c) the relative humidity at the exit of the humidificationsection.
Kinetic and potential energy can be ignored.
