Alcohol flows through two capillary tubes under a constant pressure head the diameters of the two tubes are in the ratio of `4:1` and the lengths are in the ratio `4:1` Compare the rates of flow of alcohols through the two tubes .

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

The heat is flowing through two cylinderical rods of same material. The diameters of the rods are in the ratio 1:2 and their lengths are in the ratio 2:1 . If the temperature difference between their ends is the same, the ratio of rates of flow of heat through them will be

A liquid flows through two capillary tubes A and B connected in series. The length and radius of B are twice that of A. What is the ratio of the pressure difference across A to that across B ?

Two liquids are allowed to flow through two capillary tubes of length in the ratio 1:2 and radii in the ratio 2:3 under the same pressure difference. If the volume rates of flow of the liquids are in the ratio 8:9 the ratio fo their coefficients of viscosity is

water is flowing through a tube of non-uniform cross-section. If the radii of the tube at the ebtrance and the exit are in the ratio 3:2 then the ratio of the velocites of flow of watern at the entrance and the exit is

When two capillary tubes of different diameters are dipped vertically, the rise of the liquid is

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

Water flows in a stream line manner through a capillary tube of radius a. the pressure difference being P and the rate of the flows is Q. If the radius is reduced to (a)/(4) and the pressure is increased to 4P, then the rate of flow becomes
