4) [18] Combustion products flow through the nozzle of a jet engine operating at steady state, with inlet and exit properties shown in the table. Find the mass flowrate through the nozzle, the inlet cross sectional area, and the rate of heat loss from the nozzle. You definitely need to include the kinetic energy term in the energy equation. Use air properties - it's a reasonable approximation because both air and combustion products are mostly N2. It probably seems weird to see the exit pressure being above atmospheric pressure, but that's actually possible for high-speed flows. Property Temperature Pressure Nozzle inlet value 1035 K 4.35E5 Pa Velocity 65 m/s Cross sectional area Ai Nozzle exit value 865 K 2.31E5 Pa 550 m/s 0.3 m3 4) [18] Combustion products flow through the nozzle of a jet engine operating at steady state, with inlet and exit properties shown in the table.
