Chapter 14.7, Problem 87P
Humid air is to be conditioned in a constant-pressure process at 1 atm from 39°C dry bulb and 50 percent relative humidity to 17°C dry bulb and 10.8°C 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) Determine the heat removal by the cooling coils, the heat addition by the heating coils, and the net heat transfer for the entire process, all in kJ/kg dry air.

Moist air at 105 kPa, 30° C and 80% relative humidity
flows over a cooling coil in an insulated air-conditioning
duct. Saturated air exists the duct at 100kPa and 15°C.
The saturation pressure of water at 30° C and 15°C are
4.24 kPa and 1.7 kPa, respectively. Molecular weight of
water is 18 g/mol and that of air is 28.94 g/mol. The
mass of water condensing out from the duct is ...
g/kg of dry air (round off to 2 decimal places).
Air at 0° C and 95% relative humidity has to be heated and humidified to 25° C and 40% relative humidity by the following three processes: (a) preheating; (b) adiabatic saturation in a recirculated water air-washer; and (c) reheating to final state. Calculate: 1. The heating required in two heaters; 2. The makeup water required in washer and temperature of washer. Assume effectiveness of washer as 80 per cent
