A capillary tube is attached horizontally to a constant pressure head arrangement. If the radius of the capillary tube is increased by `10%`, then the rate of flow of the liquid shall change nearly by

A capillary tube is attached horizontally to a constant head arrangement. If the radius of the capillary tube is increased by 10% ther the rate of flow of liquid will change nearly by

The radius of the capillary tube increased 0.2% then the percentage increase in the rate of flow of liquid through it is

The rate of flow of a liquid through a capillary tube is

When water flows at a rate Q through a capillary tube of radius r placed horizontally a pressure difference p develops across the ends of the tube. If the radius of the tube is doubled and the rate of flow halved the pressure difference becomes

A capilary tube is kept vertical and made to touch the surface of the liquid of surface tension T . If the radius of the capillary tube is 'r' . Then the force on the wall of the capillary tube is
