n a tank with a volume of 400 cm3, there is steam at ~550 kPa pressure and 92% quality. Mass and calculate enthalpy (m=V/v (gram, kg,.. ), Total volume/Specific volume, Enthalpy H=m x h kJ/g, kg,.... Warning: The temperature of the steam is unknown, pay attention to the units. You can use the links below. v = vf(1-x) + vg (x) [cm3 /g] h =hf(1-x) + hg (x) [kJ/kg ]
