Relations for binary mixtures

Binary coefficients such as binary diffusion coefficients, Henry coefficients. More...

Description

Binary coefficients describe the relations of a mixture of two components. Typical binary coefficients are Henry coefficients or binary molecular diffusion coefficients.

Parameters
Mmolar masses \(\mathrm{[g/mol]}\)
SigmaNuatomic diffusion volume
temperatureThe temperature \(\mathrm{[K]}\)
pressurephase pressure \(\mathrm{[Pa]}\)

This function estimates the diffusion coefficients in binary gases using to the method proposed by Fuller. This method and is only valid at "low" pressures.
