Q9/ Steam initially at 10 bar and 0.25 dryness fraction (i.e. quality = 85%). Expands down to p2 = 3.5 bar According to the hyperbolic law PV=constant, Determine 1- The final of the steam. 2- The change of temperature of the steam. 3- The work done kg during the change. 4- The change in internal energy. 5- The amount of heat supplied (g).
