The mass flow through the nozzle at station one refers to the rate at which mass of a fluid flows through a specific point or location (station one) within the nozzle or flow passage. It’s a measure of how much mass of the fluid passes through a cross-sectional area per unit of time.
- ṁ₁: Mass flow rate at station one (kg/s)
- 𝜌₁: Density of the fluid at station one (kg/m³)
- u₁: Velocity of the fluid at station one (m/s)
- A₁: Cross-sectional area of first throat at station one (m²)
