This question requires the use of the Thermodynamic Property Tables supplied as additional material. 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. • (i) Evaluate the temperature and the dryness fraction at the start of the process. (ii) 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. • (iii) Finally, the system undergoes an isentropic process such that it finishes as a saturated liquid.

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. • (i) Evaluate the temperature and the dryness fraction at the start of the process. (ii) 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. ● • (iii) Finally, the system undergoes an isentropic process such that it finishes as a saturated liquid. Evaluate the temperature at this final state. • (iv) 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.
