Latent Heat of Vaporization (\( H_V \)):

\[ H_V = 2.32 \left[1094 - 1.026 \times (T + 17.78)\right] \times \left[1 + 2.4962 \exp(-21.73M)\right] \]

Where:

• \( H_V \) is the latent heat of vaporization, in KJ/kg.
• \( T \) is the air temperature, in degrees Celsius (°C).
• \( M \) is the moisture content, in decimal dry basis.
