The air in the engine cylinder of Problem 3.156 loses the heat to the engine coolant at 100◦C. Find the entropy generation (external to the air) using constant specific heat.

Data from Problem 3.156

One kilogram carbon dioxide at 100 kPa, 400 K is mixed with 2 kg carbon dioxide at 200 kPa, 2000 K, in a rigid, insulated tank. Find the final state (P, T) and the entropy generation in the process using constant heat capacity from Table A.5.
