1. Find the specific reversible work for a steam turbine with inlet 4 MPa, 500?C and an actual exit state of 100 kPa, x = 1.0 with a 25?C ambient.
2. A steam turbine receives steam at 6 MPa, 800?C. It has a heat loss of 49.7 kJ/kg and an isentropic efficiency of 90%. For an exit pressure of 15 kPa and surroundings at 20?C, find the actual work and the reversible work between the inlet and the exit.
