Calculation of theoretical air demand (V₀)

For gaseous fuels:

When Q_L <10455kJ/(standard)m³, the formula is:

When Q_L >14637kJ/(standard)m³, the formula is:

In the formula:

V₀—the amount of theoretical air required for fuel combustion, m³(standard)/kg or m³/m^3;

Q_L—the fuel application base low calorific value, kJ/kg or kJ/(standard) m³.
