Total heat energy consumed by the engine
Input(s)
\(w_{f}\): Mass Rate of Fuel Consumption \((\mathrm{lbm} / \mathrm{min})\)
\(\mathrm{H}\): Heating value of Fuel ( \(\mathrm{ft} \mathrm{lbf} / \mathrm{Btu})\)
Output(s)
\(Q_{i}\): Total Heat Energy consumed by the Engine (hp)
Formula(s)
\[
Q_{i}=\frac{w_{f} H}{33,000}
\]
