Indicated Horsepower Help

This calculator uses the following equation:

Horsepower = (MEP * Displacement * RPM) / 792,000
Horsepower = (P * L * A * N) / 33,0000

• MEP = Mean Effective Pressure
• P = MEP
• L = Length of stroke
• A = top surface area of a piston
• N = Numbers of power strokes per minute

Note: The calculator here solves for the first equation.
