Answer #1

All the above data are taken from Property tables as given in Thermodyamics 9E by Cengel and Boles. Since the given values T = 202oC and P1 = 9.9 bar and P2 = 1.7 bar can not be found directly in property tables, double linear interpolation process of finding the necessary values is explained in detail above.
