The velocity of a crosshead piston in an aircraft engine can be calculated using the following formula:
- ṁ = Mass Flow Rate (in kilograms per second, kg/s)
- A = Cross-Sectional Area through which the fluid or gas flows (in square meters, m²)
- V = Velocity of the fluid or gas (in meters per second, m/s)
- ρ = Density of the fluid or gas (in kilograms per cubic meter, kg/m³)
