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