The principle of energy conservation states that the total energy in the lower-pressure state must equal the total energy in the higher-pressure state. 1  Therefore, the amount of heat in the flash steam and condensate must equal that in the initial condensate of 671 kJ. Steam tables give the following information: 1  Total enthalpy of saturated water at atmospheric pressure (hf) = 419 kJ/kg. 2  Total enthalpy in saturated steam at atmospheric pressure (hg) = 2 675 kJ/kg. 3  Therefore, at the lower pressure state of 0 bar g. 4  Total enthalpy in the water = 0.888 kg x 419 kJ / kg = 372 kJ (A)
