State 1. Go to table A-3 with P = 20 bar and T = 280C. At 20 bar, Tsat = 212.4 C Since TTsat SHV From Table A-4 with 20 bar and 280C, V = 0.1200 m/kg, h = 2976.4 KJ State 2. Go to Table A-3 with P = 7 bar and T = 180C. At 7 bar, Tsat = 165C Since T Tset = SHV Kg From Table A-4 with 7 bar and 180C, V = 0.2847 m/ks, h = 2799.1 KJ/Kg 1/2 S Vel = ((80 m) + [212976.4 - 2799.1) KJ | 10 Nm | Kg.m Velz 600.8 m/s xg 1 KJ 2 = 3.3 10=10|17| m. m = m K 103 Nm = Kg
