The term “cylinder piston” typically refers to the piston within a cylinder of an internal combustion engine, such as a piston engine used in aircraft. To calculate the cross-sectional area of the piston, you can use the formula for the area of a circle, as the cross-section of the piston is generally circular in shape
- A is the cross-sectional area through which air enters (in square meters, m²).
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the air density in kilograms per cubic meter (kg/m³).
- V is the velocity of the air entering the engine (in meters per second, m/s).
