I need this question in 1 hour, I will give you a good review......... A saturated mixture of 2 kg of liquid water and 0.7 kg of steam is heated at a constant pressure of 40 bar until its temperature reaches 300 oC. (a) Evaluate the temperature and the dryness fraction at the start of the process. (b) Given that the heat transfer to a system during a constant pressure process is equal to the increase in enthalpy of the system, calculate the heat transfer to the system in the process described above. (c) Finally, the system undergoes an isentropic process such that it finishes as a saturated liquid. Evaluate the temperature at this final state. (d) Sketch the two processes on a plot of temperature.v.specific entropy. Include on your sketch the two-phase region and the isobar passing through states 1 and 2.
