Latent heat of water phase changes changes with pressure - at critical point it's zero. At atmospheric pressure, it's given by countless tables all over the net. I can read the pressure and temperature of the phase change for a range of pressure values from the diagram too. But I never found any resource that would show how the latent heat value changes.
Could someone provide some table, equation, graph that gives these values? I would prefer an answer in joules if possible. If you can provide values for a range of pressures, that would be even more welcome, but I specifically want the latent heat of fusion and vaporization of water at 620Pa?
And if that was to be too hard, maybe provide just the values right at the edge of the triple point - if liquid water at just above 0 Celsius degrees is depressurized from 620 to 610Pa, how much of it will evaporate and how much will freeze?
I'm aware of a previous question here, which asks about the general effect of pressure on latent heats and the mechanisms behind said changes. Here I'm asking for a specific reference to the values for water as a function of pressure, and particularly for pressures as low as 620 Pa (which is too low for most obvious search results).
