Using the equation below, we can calculate the specific volume and volume of steam at 20kPa and 35% quality. Calculate the specific enthalpy. Warning: The temperature of the steam is unknown. v=vf(1x)+vg(x)[m3/kg]h=hf(1x)+hg(x)[kJ/kg] Here; vf: specific fluid volume [cm3/g] vg: specific steam volume [cm3lg] hf: specific fluid enthalpy [kJ/kg] hg: specific vapor enthalpy [kJ/kg]
