 Sc = viscosity/density/diffusivity
The Schmidt number is defined as a dimensionless quantity that expresses relationship between mass diffusivity and momentum diffusivity. It is a dimensionless parameter that is analogous to the Prandtl number or mass transfer. The Schmidt number is often used in determining behavior in mass transfer in binary systems between phases.
We designed a program that would calculate Schmidt numbers for low density gases and liquids at infinite dilution for binary mixtures of your choice of 28 compounds. The first program, which calculates Schmidt numbers for gases, can be utilized by simply providing the two compounds, mole fraction, temperature, and pressure. The second program calculates Schmidt number given a solvent, solute, and temperature. Both functions require data loaded from start301.
