A tube of length L and radius R is joinced to another tube of length `(L)/(3)` and radius `(R)/(2)`. A fluid is flowing through this joint tube. If the pressure difference across the first tube is `P` then pressure difference across the second tube is

There capillaries of length l, 2l and l//2 are connected in series. Their radii are r, r//2 and r//3 respectively. If stream line flow is maintained and the pressure difference across the first capillary tube is P_(1) , find the pressure difference across (i) the second and (ii) the thired capillary tube.

A tube of radius R and length L is connected in series with another tube of radius (R)/(2) and length (L)/(8) if the pressure across the tubes taken together is P, the pressure across the two tubes separately are:

The rate of flow of water in a capillary tube of length l and radius r is V. The rate of flow in another capillary tube of length 21 and radius 2 r for same pressure difference would be

The rate of steady volume flow of water through of capillary tube of length 1 and radius r, under a pressure difference of p is V. This tube is connected with another tube of the same length but half the radius, in series. Then, the rate of steady volume flow through them is (The pressure difference across the combination is p)

The rate of steady volume flow of water through a capilary tube of length and radius r under a pressure difference of Pis V. This tube is connected with another tube of the same length but half the radius in series. Then the rate of steady volume flow through them under same pressure difference across the combination is
