A piston/cylinder contains air at 300 K and 100 kPa. A reversible polytropic process with n = 1.3 brings the air to 500 K. Any heat transfer if it comes in, is from a 325°C reservoir and if it goes out, it is to the ambient at 300 K. Find the specific entropy generation (in J/kg K) (external to the air) in the process.
Enter numerical value using the virtual keypad. Round off where necessary.
