Compressed Water and Superheated Steam

Calculate specific volume (v), specific internal energy (u), specific enthalpy (h) and specific entropy (s) for compressed water and superheated steam as a function of temperature (T) at a fixed pressure (p). The properties can be calculated at different increments of temperature, outputting up to 101 values for each property. Users may select the precision of the output values and may choose either SI or US Customary units.
