Morton Number
Morton number, abbreviated as Mo, a dimensionless number, is the shape of bubbles or drops moving in a surrounding fluid or continuous phase.

\(\large{ Mo }\) = Morton number | \(\large{dimensionless}\) | |
\(\large{ g }\) = gravitational acceleration | \(\large{\frac{ft}{sec^2}}\) | \(\large{\frac{m}{s^2}}\) |
\(\large{ \mu }\) (Greek symbol mu) = dynamic viscosity of surrounding fluid | \(\large{\frac{lbf-sec}{ft^2}}\) | \(\large{ Pa-s }\) |
\(\large{ \Delta \rho }\) = density differential in the phases | \(\large{\frac{lbm}{ft^3}}\) | \(\large{\frac{kg}{m^3}}\) |
\(\large{ \rho }\) (Greek symbol rho) = density of surrounding fluid | \(\large{\frac{lbm}{ft^3}}\) | \(\large{\frac{kg}{m^3}}\) |
\(\large{ \sigma }\) (Greek symbol sigma) = surface tension coefficient | \(\large{\frac{lbf}{ft}}\) | \(\large{\frac{N}{m}}\) |
