1. The problem statement, all variables and given/known data Finding the enthalpy of water with the following known data: Water, temperature 45 degrees, pressure 1.2 bar 2. Relevant equations Q' = m'(steam) * h(gas) - m'(steam) - h(fluid) 3. The attempt at a solution I need to find the enthalpy of water under the circumstances above, to calculate a quantity of heat transferred by condensing steam. However I seem to be unable to find the enthalpy of the fluid. All attempts to find the enthalpy, I end up with either tables of saturated water or compressed water at pressures way above 1.2bar. Anybody can help me with the problem?
