What is the specific heat capacity of moist air? Thank you
The specific heat capacity of moist air is generally obtained by adding the specific heat capacity of dry air to that of water vapor. Within the range of 0–120 degrees Celsius, it can be calculated using the following formula: Ch = Cg + Cw * H = 1.005 + 1.884H. Here, Ch represents the specific heat capacity of moist air, in kJ/(kg of dry air·degree Celsius); Cg is the specific heat capacity of dry air, in kJ/(kg of dry air·degree Celsius); Cw is the specific heat capacity of water vapor, in kJ/(kg of water vapor·degree Celsius); and H represents the moisture content of the air, in kg/(kg of dry air). For more details, refer to the section on drying in the principles of chemical engineering. This post was last edited by liyingt on 2009-2-25 at 13:46
The problem now is to find a way to measure the humidity of the air, and then perform the calculations using the formula provided above.
