Assume that the initial temperature Table E.1 was 29C but the saturation pressure at 7C is desired without extrapolation since this may cause some calculation errors. Use the Clausius-Clapeyron equation and approximate the saturation pressure of water at 7C. Compare this value to the actual value on the steam table and make a comment. Question 2 (Homework) Repeat the same exercise for saturation pressure at 15C. Question 3 Superheated steam exists at 500kPa and 500C. Prove that the Maxwell relation for constant pressure and temperature system is true. Question 4 Verify using steam at 800kPa and 260C, that the following Maxwell relationship is true: (sh)p=T APPENDIX
