IAPWS

IAPWS95

HEAVY17

<code>IAPWS</code> and <code>IAPWS95</code> contain constants relative to
 ordinary water substance.
 <code>HEAVY17</code> is the same but for heavy water.

Implementation of some of the formulations for the thermodynamic
and transport properties released by the International Association for
the Properties of Water and Steam (IAPWS). More specifically, the
releases R1-76(2014), R5-85(1994), R6-95(2018), R7-97(2012), R8-97,
R9-97, R10-06(2009), R11-24, R12-08, R15-11, R16-17(2018),
R17-20 and R18-21 at <https://iapws.org>.
