Unformatted text preview: Assume constant specific heat values for air at 27 C. (a) What is the temperature of air ( C) at the diffuser exit? (b) Calculate the velocity of air (m/s) at the diffuser exit. SP18: In a turbojet engine, air enters a poorly-insulated turbine at 4.3 bar and 1320 K and exits at 2.2 bar. The turbine produces 200 kJ/kg of work. Air then enters an adiabatic nozzle and is discharged at 640 K and 0.25 bar with a velocity of 1040 m/s. Neglect velocity change of air through the turbine and consider variable specific heats for air. (a) What is the temperature of air ( C) at the nozzle inlet? (b) Determine the heat transfer (kJ/kg) and its direction for the turbine....
