YOUNG-LAPLACE EQUATION Equation of Capillarity
- Pressure inside a drop or bubble (like a balloon)
is always greater than in the continuous phase
(air outside the balloon). - As the radius becomes smaller, the pressure
becomes larger
2
Liquid Thread Break-Up
- Make a thread of liquid using say Kero syrup
- Where the cross sectional area is small, there is
a higher curvature resulting in high pressure.
Where the cross sectional area is large there is
lower curvature resulting in lower pressure. This
leads to flow from high pressure to low pressure
causing break-up of the liquid thread.
