Moist air at 55 oF dry bulb temperature and 40% relativehumidity is first heated through a heating coil. The air is thenadiabatically humidified by saturated water vapor at 4.5 psia. Theexit air has a dry bulb temperature of 90 oF and wet bulbtemperature 65 oF. Air is supplied at a volume flow rate of 478.5cfm. Assume sea level pressure throughout. Determine thefollowing.
a) Show the inlet and outlet air condition clearly on thepsychrometric chart clearly marking them as 1 and 2respectively.
b) Show the sensible heating process and humidification processon the psychrometric chart clearly marking them. Draw the overallprocess line.
c) Calculate the heat transfer rate of the heating coil. Showyour calculation.
d) Calculate the mass flow rate of the water vapor. Show yourcalculation.
e) What is the SHF value? Show clearly how you obtained it.
