Metastable Steam

Calculate specific volume (v), specific internal energy (u), specific enthalpy (h) and specific entropy (s) as a function of the quality (the percentage of vapor at equilibrium, Q) for metastable steam in the 95 – 100% vapor region. The properties can be calculated at different increments of Quality (Q), outputting up to 21 values for each property. Users may select the precision of the output values and may choose either SI or US Customary units.
