Question
Chapter 22, Problem 22.30E
Interpretation Introduction
Interpretation:
The expected contact angle when a capillary of bore radius
Concept introduction:
Surface tension effect shows itself in systems where a cylindrical solid surface is present. A very narrow cylindrical surface is called a capillary. When a capillary is immersed into a liquid, the surface tension that exists at the liquid-vapor interface will act according to the Laplace-Young equation
