Argon enters an insulated turbine operating at steady state at 1000 C and 2 MPa and exits at 350 kPa. The mass flow rate is 0.5 kg/s. Plot each of the following versus the turbine exit temperature in C:
a) the power developed, in kW
b) the rate of exergy destruction in the turbine, in kW
c) the exergetic turbine efficiency
For argon, use the ideal gas model with k = 1.67. Ignore the effects of motion and gravity. Let T0 = 20 C and P0 = 1 bar.
