      Parameters
      ----------
      target : OpenPNM Object
          The object for which these values are being calculated.  This
          controls the length of the calculated array, and also provides
          access to other necessary thermofluid properties.
  
      k : float
          Constant parameter specific to fluid
  
      temperature : string
          The dictionary key containing the temperature values (K)
  
      critical_temperature : string
          The dictionary key containing the critical temperature values (K)
  
      molar_density : string
          The dictionary key containing the molar density values (K)
