In aircraft design, the term “O type piston engine” isn’t a standard classification or widely recognized nomenclature for piston engines. To calculate the velocity of air or fuel within a piston engine, you would typically use the general formula for velocity:
- V is the velocity in meters per second (m/s).
- ṁ is the mass flow rate of air or fuel 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 component (e.g., intake or exhaust) through which the fluid flows in square meters (m²).
