How This Is Calculated


$$ W = \frac{0.622 \cdot p_v}{p - p_v} $$ where:

W   =   Humidity Ratio   (Dimensionless)

pv   =   Partial pressure of water vapor   (Pa)

p   =   Total pressure of the air   (Pa)


Assumptions


  • Dry air and water vapor behave as ideal gases
  • Molecular weights remain constant.
  • There is no condensation.
  • Pressure remains uniform.
