A liquid is flowing in a horizontal uniform capillary tube under a constant pressure difference P . The value of pressure for which the rate of flow of the liquid is doubled when the radius and length both are doubled is

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

The volume of a liquid flowing per second through a capillary tube under a constant pressure difference is directly proportional to the_________power of radius.

A liquid flows through a horizontal tube of variable diameter. Then the pressure is lowest where

If Q is the rate of flow of liquid through a capillary tube of length l and radius r at constant pressure P, then the rate of flow of liquid through a capillary tube when radius is reduced to one third and length of tube is doubled

The rate of a flow V a of liquid through a capillary under a constant pressure depends upon (i) the pressure gradient (P/l) (ii) coefficient of viscosity of the liquid eta (iii) the radius of the capillary tube r. Show dimesionally that the rate of volume of liquid flowing per sec V∝ Pr^4 /ηl

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

The rate of flow of a liquid through a capillary tube of radius r is under a pressure difference of P. Calculate the rate of flow when the diameter is reduced to half and the pressure difference is made 4 P?
