When a capillary tube of small diameter D is inserted into a container of liquid, the liquid
Question:
When a capillary tube of small diameter D is inserted into a container of liquid, the liquid rises to height h inside the tube (Fig. P7–113). h is a function of liquid density ρ, tube diameter D, gravitational constant g, contact angle Ф, and the surface tension σs of the liquid.
(a) Generate a dimensionless relationship for h as a function of the given parameters.
(b) Compare your result to the exact analytical equation for h given in Chap. 2. Are your dimensional analysis results consistent with the exact equation? Discuss.
