SUMMARY
The discussion focuses on calculating the mass flow rate and exit flow area for air in a control volume under steady-state conditions. The mass flow rate is determined using the equation m' = ρvA, where ρ is the air density calculated from the ideal gas law (ρ = p/RT). The calculated mass flow rate is 0.351 kg/s, and it is confirmed that the mass flow rate remains constant in steady-state conditions. The exit flow area can be derived from the mass flow rate and exit conditions.
