That sounds like a mixture of phases. The specific heat of water decreases at the boiling point. The specific heat of steam is about half that of liquid water, but it's more the heat transfer coefficient that is relevant there. If you're talking about the specific heat of liquid, it does not change discontinuously anywhere. > > The water pump pressure feeding the E-Cat could be very high relative to > atmospheric pressure, and the pressure drop at the exit from the E-Cat > could be quite substantial prior to the thermocouple, resulting in a dry -- > even superheated -- steam. > No, it would not convert from liquid to dry steam unless the temperature of the liquid water was over 600C, and that would require implausible pressures. > So my originally post problem of estimating the pressure at the output > thermocouple still stands as critical in invalidating the Oct 28 > demonstration. > > You'll have to explain it again for those of us with shit for brains, because it doesn't make sense to me. I don't see how you've countered the very simple claim that the well regulated temperature corresponds to a 1% regulation in power, unless there is a mixture of phases.
