Humid Air : Specific heat capacity

Air psychrometrics

1. Introduction

The absolute humidity is calculated from the specific heat of dry air and the specific heat of water ponderated by the absolute humidity.

2. Calculation

Cp' = 1005 + 1884*ω
With :
ω = Absolute humidity of air (-)
Cp' = specific heat of humid air (J/K/kg_dry_air)
