Indicated Power of 2 Stroke Engine

Go Indicated Power of 2 Stroke Engine = (Indicated Mean Effective Pressure*Piston Area*Stroke of Piston*RPM*Number of Cylinders)/60

Indicated Power of 4 Stroke Engine

Go Indicated Power of 4 Stroke = (Indicated Mean Effective Pressure*Piston Area*Stroke of Piston*(RPM/2)*Number of Cylinders)/60

Work Done per Cycle

Go Work = Indicated Mean Effective Pressure*Piston Area*Stroke of Piston

Area of Piston given Piston Bore

Go Piston Area = (pi/4)*Piston Bore^2
