7: The heat transfer explicitly for the reversible steady flow process 1-2-3-4-5-3 is shown in the figure. a Calculate the total heat transfer in kJ by showing each heat transfer in each process explicitly if the mass of the body is 9 kg. b. If the heat transfer is 83 kJ during the process 3-4-5-3-2, determine the mass of the body. ec) 930 500 200 0.1 0.3 0. 13

Water undergoes two processes in series: • 1 to 2: isentropic (internally reversible and adiabatic) compression from 0.1 MPa and the phase of water is “saturated vapor” to 0.5 MPa• 2 to 3: a reversible isothermal process to 1.5 MPaa) 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 to 3 a compression, expansion, or isochoric process? How do you know? c) Determine the overall specific work (w13) and specific heat transfer (q13) for this complete process. (Hint: recall that Q int rev =∫ T ds21 for an internally reversible process between states 1 and 2.)
