class  RichardsDensityMethane20degC
 Methane density - a quadratic fit to expressions in: "Results of (pressure, density, temperature) measurements on methane and on nitrogen in the temperature range from 273.15K to 323.15K at pressures up to 12MPa using new apparatus for accurate gas-density" This is only valid for p>=0, which is the physical region.
