One kilogram of air undergoes the following two internally reversible processes in a closed system. Process 1-2: The air is compressed adiabatically from P₁ = 100 kPa and T₁ - 300 °K to P₂ =2 P₁. Process 2-3: It is then heated at constant pressure until T3 - 560 °K. Calculate (a) the specific volumes of the air at states 1, 2 and 3 (b) the work and heat transferred between states 1 and 3 (c) the entropy change between state 1 and 3. Draw the processes on a T-s diagram and USE THE AIR TABLE A-17 FOR YOUR CALCULATIONS. One kilogram of air undergoes the following two internally reversible processes in a closed system.
