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.

Three capillary tubes of the same radius r but of lengths l_(1),l_(2)andl_(3) are fitted horizontally to the bottom of a tall vessel containing a liquid at constant head and flowing through these tubes. Calculate the length of a single outflow tube of the same radius r which can replace the three capillaries.

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.

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 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?

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

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
