A non-ideal gas enters a turbine at 1000 kPa and 800 K at a rate of 1.0 kg/s and exits at 100 kPa and 300 K. The surrounding is at 100 kPa and 300 K. During the process, the gas loses 600 kJ/kg of heat to the surrounding. Note that this non-ideal gas follows the equation of state where a = 0.002 m3 /kg. The non-ideal gas has the average specific heat of != 2.80 kJ/kg-K and the gas constant of R = 0.52 kJ/kg-K. [Hint: You may need generalized dh and/or ds relations.] (a) The maximum possible work out from this process. (b) The actual work out. (c) The second law efficiency of the process
