Cappilary And Cappilary Rise

A cappilary of diameter d mm is dipped in water such that the water rises to a height of 30 mm. If the radius of the capillary is made ((2)/(3)) of its previous value, then compute the height up to which water will rise in the new capillary ?

The rise of a liquid in a capillary is due to

Water flows in a streamline manner through a cappilary tube of radius a. The pressure difference being P and the rate of flow is Q . If the radius is reduced to a//2 and the pressure difference is increased to 2P, then find the rate of flow.

What is the reason for capillary rise?

The liquid rise in capillary-

1^(@) C rise in temperature is equal to a rise of
