**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.*- is normally accurate enough^{o}C) - For higher accuracy - a value of
*c*_{p}=*1.006 kJ/kg.K (equal to kJ/kg.*- is better^{o}C) - For highest accuracy - the value of the specific heat capacity of air should be interpolated to the temperature
