Question:
A gas turbine operating at steady-state is shown in the following figure. Air enters the compressor with a mass flow rate of 5 kg/s at 0.95 bar and 22°C and exits at 5.7 bar. The air then passes through a heat exchanger before entering the turbine at 1100 K, 5.7 bar. Air exits the turbine at 0.95 bar. The compressor and turbine operate adiabatically and the effects of motion and gravity can be ignored. The compressor and turbine isentropic efficiencies are 82 and 85%, respectively. Using the ideal gas model, determine, each in kW,
a) The net power developed;
b) The rates of exergy destruction for the compressor and turbine;
c) The net rate of exergy carried out of the plant at the turbine exit (so state 4 compared to state 1).
Let T0 = 22°C and p0 = 0.95 bar.
