In aircraft design, “flat engines” typically refer to horizontally opposed engines with a flat or boxer configuration. To calculate the velocity of air or fuel within a flat engine, you can use the formula for velocity, which is applicable to fluid flow within the engine:
- 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).
- P is the density of the fluid (air or fuel) in kilograms per cubic meter (kg/m³).
- A is the cross-sectional area through which the fluid flows in square meters
