Mass Transfer Coefficient (\( K_g \)):

\[ K_g = 0.008489 - 0.000225T + 0.000236 \text{RH} - 0.00042Q \]

Where:

• \( K_g \) is the mass transfer coefficient, in moisture decimal dry basis-cm²/h-m²-kg.
• \( T \) is the temperature of drying air, in degrees Celsius (°C).
• \( \text{RH} \) is the relative humidity, in percentage (%).
• \( Q \) is the airflow rate of drying air, in cubic meters per minute (m³/min).
