The term “Density of RPM of engine” is a standard engineering parameter, RPM (Revolutions Per Minute) is a measure of rotational speed, typically referring to the speed of an engine’s crankshaft or a rotating component.
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- P = Pressure of the fluid (in pascals, Pa)
- R = Specific gas constant for the fluid (in J/(kg·K))
- T = Temperature of the fluid (in kelvin, K)
