The temperature and pressure at the inlet of a gas turbine are measured as 325 OC and 500kPa. The gas expands isentropically in the turbine and the pressure gets reduced to 150kPa at the exit. Determine the gas temperature at the exit after expansion. Heat is added at constant volume to increase the temperature of the gas to 300 OC to continue with the next cycle. Determine the heat added to the gas. Assume R=287 J/kg.K and Cp/Cv=1.4;

Mr Luda wants to understand further about a newly created gas. The gas is initiallyat a pressure of 90 kPa, volume of 1.258 m3 and temperature of 10°C (State 1).The gas undergoes a 3-step process in which it is first compressed isothermally toa pressure of 400 kPa and volume of 0.283 m3 (State 2), then expanded at constantpressure back to its original volume (State 3). Finally, the gas is returned to itsoriginal State 1 by cooling at constant volume.a) Sketch the cycle of this system on a P – V diagram.b) Calculate the work done (in kJ) for each process step.c) Determine the total work done for the three-process cycle.d) State whether the work done is on or by the system.
