Bond Number

Bond number, abbreviated as Bo, is a dimensionless number that represents the relationship of gravitational force to surface tension force.  In Europe, the Bond number is known as the Eötvös number and is abbreviated Eo.  When used with the Morton Number, it is used to characterize the shape of bubbles or drops moving within a fluid.

	Bond Number formulas \(\large{ Bo = \frac { \rho \; a \; l^2}    {\sigma}  }\)    Where: \(\large{ Bo }\) = Bond number \(\large{ a }\) = acceleration \(\large{ \rho }\)  (Greek symbol rho) = density \(\large{ l }\) = length \(\large{ \sigma }\) = surface tension

This number should not be confused with the James Bond number which, at the time of authorship, is eleven.
