The “Bond Number” B4. 0 or “Eötvös Number” is a formula used in fluid dynamics that shows the importance of gravitational forces compared to surface tension forces and is used to describe the shape of a droplet moving in a surrounding fluid. To find the bond number we apply the formula where ρ represents the density of the liquid, g represents the acceleration due to gravity, D is the diameter of the droplet, and σ is the surface
temperature. What is D in terms of B4. 0 , ρ, g, and σ?
