Heat Supplied (\( Qsd \)):

\[ Qsd = \frac{60 \times (H2 - H1) \times AR}{\gamma} \]

Where:

• \( Qsd \) is the heat supplied to the dryer, in kilojoules per hour (KJ/hr).
• \( H2 \) is the enthalpy of the drying air, in kilojoules per kilogram of dry air (KJ/kg da).
• \( H1 \) is the enthalpy of the ambient air, in kilojoules per kilogram of dry air (KJ/kg da).
• \( AR \) is the airflow rate, in cubic meters per minute (m³/min).
• \( \gamma \) is the specific volume, in cubic meters per kilogram of dry air (m³/kg da).
