Saturated Steam Table

hg(p=0.5 Mpa) = 2746.4 + (2758.1-2746.4)/(0.6178-0.4758)*(0.5-0.4758)

=2748.4 kJ/kg for 100% quality saturated vapor

p (Mpa)

hg (kJ/Kg)

Example: If the quality is 50% and the temperature is 150? C

hf = 632.2, hfg = 2114.2, hg = 2746.4

h = (1-x) hf + x hg = (1-0.5)(632.2) + 0.5(2746.4)

= 1689.3 (kJ/kg)

hf (kJ/kg)

hfg (kJ/kg)
