Steam in Vapor/Liquid Mixture and Calculate Entropy, Heat Flow and Internal Energy Exchange

Question

Expanding wet steam.

Steam initially in a vapor/liquid mixture with 80 percent liquid at 250C, expands isothermally and reversibly to a final state at 20 bar. Using the steam tables:

a)  Find the entropy change.
b)  Calculate the heat flow.
c)  Find the internal energy change.
d)  Calculate the work done.

Summary

The question belongs to Chemical Engineering and it is about vapor/liquid mixture expanding isothermally and reversibly to a final state. The entropy change, the heat flow, the internal energy change, etc have been measured.
