psia to 900 F on the turbine work.
7–44 A heavily insulated piston-cylinder device contains
0.05 m3 of steam at 300 kPa and 150°C. Steam is now compressed in a reversible manner to a pressure of 1 MPa. Determine the work done on the steam during this process.
7–45 Reconsider Prob. 7–44. Using EES (or other)
software, evaluate and plot the work done on the
steam as a function of final pressure as the pressure varies from
300 kPa to 1MPa.
7–46 A piston-cylinder device contains 1.2 kg of saturated
water vapor at 200°C. Heat is now transferred to steam, and
steam expands reversibly and isothermally to a final pressure
of 800 kPa. Determine the heat transferred and the work done
during this process.
7–47 Reconsider Prob. 7–46. Using EES (or other)
software, evaluate and plot the heat transferred to
the steam and the work done as a function of final pressure as
the pressure varies from the initial value to the final value of
800 kPa. Entropy Change of Inc...
