The sensible heat factor during cooling and dehumidification process is given by (where h_{1} = Enthalpy of air entering the cooling coil, h_{2} = Enthalpy of air leaving the cooling coil, and h_{A} = Enthalpy of air at the end of dehumidification process)

The total radiation from a black body per second per unit area is __________ fourth power of the absolute temperature. This statement is known as Stefan-Boltzmann law.
