The velocity of a reciprocating engine’s piston can be calculated using the following formula:
ṁ = Mass Flow Rate (in kilograms per second, kg/s)
– V = Velocity of the engine (in cubic meters, m³)
– ρ = Density of the air (in kilograms per cubic meter, kg/m³)
– A = Cross sectional area ofEngine speed (in revolutions per minute, RPM, which may need to be converted to seconds)
