To calculate the mass flow rate of air or fuel through a cylinder bore in a piston engine, you can use the same formula mentioned earlier for mass flow rate:
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the density of the fluid (air or fuel) in kilograms per cubic meter (kg/m³).
- A is the cross-sectional area of the cylinder bore through which the fluid flows in square meters (m²).
- V is the velocity of the fluid in meters per second (m/s).
