Liquid drops are falling slowly one after the other from a vertical capillary tube of bore radius 'r' If W is weight of a liquid drop , surface tension of that liquid is

Internal pressure inside a liquid drop of radius r and surface tension T is

Internal pressure inside a liquid drop of radius r and surface tension T is

The excess pressure inside the drop of a liquid of surface tension T and radius of drop r is

The weight of liquid column in a capillary tube is 11xx10^(-4)N . If the radius of tube is 7 mm, calculate the surface tension of liquid.

A liquid is coming out from a vertical tube. The relation between the weight of the drop W , surface tension of the liquid T and radius of the tube r is given by, if the angle of contact is zero

A liquid is coming out from a vertical tube. The relation between the weight of the drop W , surface tension of the liquid T and radius of the tube r is given by, if the angle of contact is zero

The work done to split a liquid drop id radius R into N identical drops is (taken sigma as the surface tension of the liquid)
