The correct expression for the Colburn $j$-factor for mass transfer that relates Sherwood number ($Sh$), Reynolds number ($Re$) and Schmidt number ($Sc$) is
1. $\frac{Sh}{\left ( Re \right )\left ( Sc \right )^{1/3}}$
2. $\frac{Sh}{\left ( Re \right )^{1/2}\left ( Sc \right )}$
3. $\frac{Sh}{\left ( Re \right )^{1/2}\left ( Sc \right )^{1/3}}$
4. $\frac{Sh}{\left ( Re \right )\left ( Sc \right )}$
