The air compressor in the core of the CFM56-5A1 turbofan engine of the Airbus A320 compressors 50 kg/s of air at 5°C and 0.8bar to 30bar. The compressor has an isentropic efficiency of 85%. Calculate the isentropic and actual temperature at exit from the compressor. You can assume for air that y = 1.4 cp = 1005 J/kg K You can assume for isentropic compression. P₂ T₁ P₁ Compressor Isentropic efficiency is n = - T25 -₁ 1₂-11 Where Ti is the temperature at the start of compression in Kelvin and T2 is the temperature at the end of compression in Kelvin. The subscript s is for temperature at the end of isentropic compression.

Thermodynamic

4) Hot combustion gases enter the nozzle of a turbojet engine at 350 kPa, 1007 °C and 95 m/s, and they exit at a pressure 100 kPa. Assuming an isentropic efficiency of 95 percent and treating the combustion gases as air determind a- The exit velocity b- The exit temperature

Water steam flows steadily through an adiabatic turbine. The inlet conditions of steam are 1.0 x 106 Pa and 600°C, one of the exit conditions is 7.5 x 10³ Pa. Assuming the process is isentropic, determine (with the help of the steam table): (a) the temperature of the steam at the exit (K). (b) the quality of the steam at the exit (%). (c) the specific enthalpy of the steam at the exit (kJ/kg). (d) the work done per unit mass by the turbine (kJ/kg).
