SUMMARY
The discussion focuses on calculating the air mass flow rate in jet engines using thermodynamic principles and specific equations. Key formulas mentioned include the thrust-to-specific impulse (Isp) equation: Total Mass Flow Rate (W) = Thrust (F) / Isp, and the fuel flow rate equation: mfuel = Fuel flow rate = mair(f/a)/(B+1). The conversation highlights the importance of knowing inlet and outlet conditions, as well as velocities, to accurately determine mass flow rates. Examples provided include the GE 90-110B engine and references to momentum balance for control volumes.
