The mass flow rate of air or exhaust gases through a turbine blade in aircraft design represents the amount of fluid that the turbine blade handles. The formula to calculate the mass flow rate (ṁ) through a turbine blade is the same as the formula for mass flow rate through a turbine, and it’s as follows:
- ṁ = Mass flow rate (in kilograms per second, kg/s)
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- A = Cross-sectional area of the turbine inlet (in square meters, m²)
- V = Inlet velocity of the fluid (in meters per second, m/s)
