1. A constant-pressure piston/cylinder contains 2 kg of water at 5 MPa and 100?C. Heat is added from a reservoir at 600?C to the water until it reaches 600?C. Find the total irreversibility in the process.
2. A constant "flow" of steel parts at 2 kg/s at 20?C goes into a furnace, where the parts are heat treated to 900?C by a source at an average of 1250 K. Find the reversible work and the irreversibility in this process.
