Two capillary tubes of lengths in the ratio `2 : 1` and radii in the ratio `1 : 2` are connected in series. Assume the flow of the liquid through the tube is steady. Then, the ratio of pressure difference across the tubes is

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

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

Two capillaries of same length and radii in the ratio 1 : 2 are connected in series. A liquid flows through them in streamlined condition. If the pressure across the two extreme ends of the combination is 1 m of water, the pressure difference across first capillary is

Two capillaries of same length and radii in the ratio 1 : 2 are connected in series. A liquid flows through them in streamlined condition. If the pressure across the two extreme ends of the combination is 1 m of water, the pressure difference across first capillary is

Two capillaries of same length and radius in the ratio of 1:2 are connected in series and a liquid flows through this system under streamline conditions . If the pressure across the two extreme ends of combination is 1m of water, what is the pressure difference across the (i) first capillary (ii) second capillary?

If two capillary tubes of radii r_1 and r_2 and having length l_1 and l_2 respectively are connected in series across a heaed of pressure p, find the rate of flow of the liqid through the tubes, if eta is the coefficient of viscosity of the liquid.

Two capillary tubes of same length each of 50 cm but of different radii 4 mm and 2mm are connected in series. When water flows, the pressure, difference between the ends of the first tube is
