SUBROUTINE MCSDIF (P, T, KDIM, RMCWRK, DJK)

This subroutine computes the binary diffusion coefficients given the pressure and temperature.

SUBROUTINE MCADIF (P, T, X, RMCWRK, D)

This subroutine computes the mixture-averaged diffusion coefficients given the pressure, temperature, and species mole fractions.

SUBROUTINE MCMDIF (P, T, X, KDIM, IMCWRK, RMCWRK, D)

This subroutine computes the ordinary multicomponent diffusion coefficients given the pressure, temperature, and mole fractions.

SUBROUTINE MCCDEX (K, KDIM, RCKWRK, COFDIF)

Gets or puts values of the fitting coefficients for the polynomial fits to species binary diffusion coefficients.
