Capillary Rise Formula

Capillary Rise Formula. Capillary Rise In Latin the word capilla means hair Due to the pressure difference across a curved liquidair interface the water rises up in a narrow tube in spite of gravity Consider a vertical capillary tube of circular cross section (radius a) inserted into an open vessel of water The contact angle between water and glass is acute.

This video explains the derivation of the capillary rise equation and discusses its practical significance in the context of soil water movement.

Capillary rise (h) = 2 T c o s θ / r ρ g Which for an angle of contact of 0o becomes Capillary rise (h) = 2T/ r ρ g Occurrence of Capillary Action Capillary action is induced by the combination of cohesive forces of the liquid and the adhesive forces between the liquid and tube material.

What Is Capillary Action? Expression for Capillary Rise/ Fall?

Capillary action is the physical phenomenon arising due to surface tension on the interface of immiscible media Commonly capillary phenomena occur in liquid media and are brought about by the curvature of their surface that is adjacent to another liquid gas or its own vapor Surface curvature in a fluid gives rise to an additional socalled.

Capillary rise : Class 11 Physics Lesson Mechanical

The ascent of a liquid column in a capillary tube is given by the following equation h = 2Scosθ/rρg − r/3 Now let’s do the capillary action formula derivation If the capillary is very narrow then we have h = 2Scosθ/rρg Where h = height of the capillary tube r is the radius of the capillary tube ρ is the density of the liquid or water.
