Specific Heat Capacity of Dry Air

The Specific Heat Capacity of dry air vary with temperature

Note! At normal atmospheric pressure of 1.013 bar - the specific heat of dry air - c_p - will vary with temperature. This may influence on the accuracy of air conditioning and industrial air handling process calculations.

• For ordinary calculations - a value of c_p = 1.0 kJ/kg K (equal to kJ/kg.^oC) - is normally accurate enough
• For higher accuracy - a value of c_p = 1.006 kJ/kg K (equal to kJ/kg.^oC) - is better
• For highest accuracy - the value of the specific heat capacity of air should be interpolated to the temperature
