The term “Velocity of RPM of engine” is a standard engineering parameter. RPM stands for “Revolutions Per Minute,” and it represents the rotational speed of an engine, typically the crankshaft’s speed. It is not a velocity in the traditional sense, which would involve the movement of an object through space over time.
- V is the velocity of the air (in meters per second, m/s).
- m is the mass flow rate (in kilograms per second, kg/s).
- Rho is the air density (in kilograms per cubic meter, kg/m³).
- A is the cross-sectional area (in square meters, m²) through which the air flows.
