pressure_spline_error(rho, Pset, T, xi, Eos)[source]

Calculate difference between set point pressure and computed pressure for a given density.

Used to ensure an accurate value from the EOS rather than an estimate from a spline.

Parameters:

  • rho (float) – [mol/\(m^3\)] Density of system

  • Pset (float) – [Pa] Guess in pressure of the system

  • T (float) – [K] Temperature of the system

  • xi (numpy.ndarray) – Mole fraction of each component, sum(xi) should equal 1.0

  • Eos (obj) – An instance of the defined EOS class to be used in thermodynamic computations.

Returns:

pressure_spline_error – [Pa] Difference in set pressure and predicted pressure given system conditions.

Return type:

float
