The mass flow through the diffuser at station two refers to the rate at which mass of a fluid flows through a specific point or location (station two) within the diffuser section of a flow passage. A diffuser is a component in fluid systems designed to slow down and increase the pressure of a flowing fluid by gradually increasing the cross-sectional area.
- ṁ₂: Mass flow rate at station two (kg/s)
- 𝜌₂: Density of the fluid at station two (kg/m³)
- u₂: Velocity of the fluid at station two (m/s)
- At,₂: Cross-sectional area of second throat at station two (m²)
