Question
From the Table (A-4 through A-6), obtain the value of specific volume at the initial and the final states. At initial pressure saturated vapour of 150 kPa 150   kPa . v 1 = v g @ 150 kPa = 1.15942 m 3 / kg v 1 = v g @ 150   kPa = 1.15942   m 3 / kg At final pressure and temperature of 150 kPa 150   kPa and 200 ° C 200 ° C . v 2 = 1.44449 m 3 / kg. I can’t find those values in the table.
