Question
Air is expanded in an internally reversible process from p1=10.29 bar and T1=1200K to a final pressure of p2= 1.00 bar.
Determine all properties of the initial and final states (T,p,v,h and u), calculate the work of the process per unit mass, and sketch the process in the T-s and p-v diagrams assuming ideal gas behavior in the 4 following cases.
- Adiabatic reversible expansion in an ideal turbine (1 inlet and 1 outlet);
- Adiabatic reversible expansion in a (closed) frictionless piston–cylinder device;
- Isothermal reversible expansion in an ideal turbine (1 inlet and 1 outlet);
- Isothermal expansion in a (closed) frictionless piston–cylinder device.
Kinetic and potential energy terms are negligible in all processes
