Estimation of Specific Heat of Superheated Water

A recently developed corresponding-states correlation of the maximum attainable liquid superheat provides an asymptote for liquid specific heats. The specific heat at any pressure approaches this asymptote in the same way as that at an arbitrary high-pressure reference, within a simple correction function. Accordingly, lower pressure data can be extrapolated accurately to within a few degrees of their own limiting superheat with the help of the correction function.
