Mass flow rate during sonic flow at the throat refers to the rate at which mass is passing through the narrowest cross-sectional area of a convergent-divergent nozzle when the fluid velocity reaches the speed of sound.
- Density of sonic flow at throat (𝜌*) in kg/m^3
- Velocity of sonic flow at throat (u*) in m/s
- Cross-sectional area of sonic flow at throat (A*) in m^2
- Mass flow rate (ṁ) in kg/s
