Question

capillary arise through concave meniscus,derive an expression
​

Answer 1

Let the capillary rise be h and be the angle of contact at the edge of contact of the concave meniscus and glass figure. If R is the radius of curvature of the meniscus then from the figure, r=R cosθ. Thus, narrower the capillary tube, the greater is the capillary rise.
