Problem 2 (20 pts) Water undergoes two processes in series: . 1 2: isentropic (internally reversible and adiabatic) compression from 0.1 MPa and the phase of water is saturated vapor" to 0.5 MPa 2 3: a reversible isothermal process to 1.5 MPa . a) Draw the overall process on a T-s diagram. Clearly indicate all states and the values of the relevant intensive properties on your diagram. b) Is process 2 3 a compression, expansion, or isochoric process? How do you know? c) Determine the overall specific work (W13) and specific heat transfer (913) for this complete process. (Hint: recall that Qint rev = S T ds for an internally reversible process between states 1 and 2.). =
