Superheated steam enters a turbine at 3 MPa, 550oC, and exits at
0.01 MPa.
a) If the process is reversible adiabatic (isentropic), find the
final
temperature (T2s), the final enthalpy (h2s) of the steam, and the
turbine
work (Wt,s).
b) What is Sgen for the above process?
c) If the isentropic efficiency is 90%, find the actual final
temperature (T2a)
and calculate Sgen?
d) Plot process (a) and (c) on a Ts diagram.
