At the inlet of a steam turbine, the pressure of the steam is P1 = 1 MPa, temperature T1 = 3000C and the outlet pressure is P2 = 7.5 kPa dryness degree x2 = 0.90. Since the ambient temperature To = 200C ambient pressure Po = 100 kPa and the changes in kinetic potential energies can be neglected; Calculate the work done by the steam. If an isentropic expansion could occur between inlet conditions and outlet pressure, how much work would the steam have to do? Show both real and isentropic expansion (with saturation curves and T, x, P, values) in the T-s diagram. Calculate the maximum work that can be obtained from unit mass steam at the specified inlet conditions. Calculate the maximum work that can be obtained from unit mass steam between inlet and outlet points.
