question 1: Consider an air standard cycle in which the air enters the compressor at 1.0 bar and 20degree celsius.
The pressure of air leaving the compressor is 3.5 bar and the temperature at the turbine inlet is 600 degree celsius.
Determine per kg of air:
(i) Efficiency of the cycle
(2)Heat supplied to air
(3)Work available at the shaft
(4)Heat rejected in the cooler
(5)Temperature of air leaving the turbine.
question 2: Agas turbine is supplied with gas at 5bar and 1000K and expands it adiabatically to 1 bar.The mean specific heat at constant pressure and constant volume are 1.0425kj/kgK and 0.7662kj/kg K respectively.
(i) Draw the temperature-entropy diagram to represent the processess of the simple gas turbine system
(ii) Calculate the power developed in kw per kg of gas per second and the exhaust gas temperature.
