Saturated Water
Tsat = Saturation Temperature (oC)
Psat = Saturation Pressure (kPa)
vf = Specific volume of saturated liquid state (m3/kg)
vg = Specific volume of saturated vapor state (m3/kg)
uf = Specific Internal energy of saturated liquid state (kJ/kg)
ug = Specific Internal energy of saturated vapor state (kJ/kg)
ufg = Change in Internal energy during evaporation (or condensation) (kJ/kg)
hf = Specific Enthalpy of saturated liquid state (kJ/kg)
hg = Specific Enthalpy of saturated vapor state (kJ/kg)
hfg = Change in Enthalpy during evaporation (or condensation) (kJ/kg)
sf = Specific Entropy of saturated liquid state (kJ/kg.K)
sg = Specific Entropy of saturated vapor state (kJ/kg.K)
sfg = Change in Entropy during evaporation (or condensation) (kJ/kg.K)
