In fluid dynamics the Eötvös number (Eo), also called the Bond number (Bo), is a dimensionless number measuring the importance of gravitational forces compared to surface tension forces for the movement of liquid front. Alongside the capillary number, commonly denoted C a {\displaystyle \mathrm {Ca} } , which represents the contribution of viscous drag, B o {\displaystyle \mathrm {Bo} } is useful for studying the movement of fluid in porous or granular media, such as soil.
