The mass flow rate of an arbitrary isentropic flow through a nozzle represents the rate at which mass is flowing through the nozzle. Mass Flow Rate is a measure of the mass of fluid passing through a specific section of a nozzle or any other conduit per unit of time. Arbitrary” implies that the specific conditions of the flow, including the geometry of the nozzle and the fluid properties, are not limited to any particular scenario and may vary. Arbitrary isentropic flow through a nozzle refers to the flow of a compressible fluid (such as a gas) through a nozzle where certain conditions are met. In this context, “isentropic” means that the process is adiabatic (no heat transfer) and reversible, which are idealized assumptions for analyzing fluid flow in nozzles.
- Mass flow rate (ṁ) in kg/s
- Area of the throat (At) in m^2
- Flow parameter (𝜓)
- Total pressure (p0) in N/m^2
- Density upstream of the nozzle (𝜌0) in kg/m^3
