A-A nozzle should produce a flow of air with 200 m/s at 20°C, 100 kPa (exit condition). It is estimated that the nozzle has an isentropic efficiency of 92%. Calculate the inlet air conditions, assuming that the inlet kinetic energy is negligible. B- 1kg of air at 10bar and 125°C receives heat at constant pressure until its temperature become 650°C, its then expands adiabatically to pressure of 1bar. Determine the change of entropy during each process and the final air temperature.
