The term “Cross-sectional area of RPM of engine” is a standard engineering parameter in aircraft design or any engineering field. RPM (Revolutions Per Minute) is a measure of rotational speed, typically referring to the speed of an engine’s crankshaft or a rotating component.
Cross-sectional area, on the other hand, typically relates to the area of a section or slice through a three-dimensional object.
- 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).
