humid heat

humid heat
the heat capacity (specific heat) of humid air, expressed per unit mass of dry air in the mixture. The engineering symbol is c. For ordinary engineering calculations in the range 0 to 50°C the following expressions are used to calculate humid heat: In , c = 0.24 + 0.45H where 0.24 BTU/lb°F is the heat capacity of dry air, 0.45 BTU/lb°F is the heat capacity of water vapor, and H is the absolute humidity in lb water vapor per lb dry air in the mixture. In units, c = 1.005 + 1.82H where 1.005 kJ/kg°C is the heat capacity of dry air, 1.82 kJ/kg°C the heat capacity of water vapor, and H is the absolute humidity in kg water vapor per kg dry air in the mixture.
