Humid air is to be conditioned in a constant pressure

Humid air is to be conditioned in a constant pressure process at 1 atm from 39oC dry bulb and 50 percent relative humidity to 17oC dry bulb and 10.8oC wet bulb. The air is first passed over cooling coils to remove all of the moisture necessary to achieve the final moisture content and then is passed over heating coils to achieve the final state.
(a) Sketch the psychometric diagram for the process.
(b) Determine the dew point temperature of the mixture at the inlet of the cooling coils and at the inlet of the heating coils.
(c) What is the net heat transfer for the entire process for this process, in kJ/kg dry air?
