Two capillary tubes of same radius r but of lengths l1 and l2 are fitted in parallel to the bottom of a vessel should be the length of single tube that can replace the two tubes so that the rate of flow is the same as before.

Two capillary tubes of the same length but different radii r and r are fitted in parallel to the bottom of a vessel. The pressure head is P . What should be the radius of a single tube that can replace the two tubes so that the rate of flow is same as before

Two capillary tubes of same radius r but of lengths l_(1) and l_(2) are fitted in parallel to the bottom of a vessel. The pressure to the bottom of a vessel. The pressure head is P. What should be the length of a singl tube of same radius that can replace the two tubes so that the rate of flow is same as before?

Three capillary tubes of same radius 1 cm but of length 1 m 2 m and 3 m are fitted horizontally to the bottom of a long vessel containing a liquid at constant pressure and flowing through these. Whatis the length of a single tube which can replace the three capillaries.

Three capillary tubes of the same radius r but of length l_1, l_2 and l_3 are fitted horizontally to the bottom of a long cylinder containing a liquid at constant head and flowing through these tubes. Find the length of a single overflow tube of the same radius r, which can replaced the three capillaries.

Two capillary tubes of same length but radii r_(1) r_(2) are arranged horizontally side by side to the bottom of a large vessel containing water. The radius of single tube of same length that can replaced them so that the rate of volume flow through it is equal to the total rate of volume flow through the two tubes is

Three horizontal capillary tubes of same radii and length L_(1),L_(2) and L_(3) are fitted side by side a little above the bottom, to the wall of a tank that is filled with water. The length of a single capillary tube of same radius that can replace the three tubes such that thwe rate of flow of water through the single tube equals the combined rate of flow through the three tubes is

Two capillary tubes of radii 0.6 cm and 0.3 cm are dipped in the same liquid. The ratio of heights through which the liquid will rise in the tubes is

16cm^(3) of water flows per second through a capillary tube of radius a cm and of length l cm when connected to a pressure head of h cm of water if a tube of the same length and radius a/2 cm is connected to the same pressure head the quantity of water flowing through the tube per second will be-

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.
