Capillary tubes of length `l` and `2l` are connected in series, their radii are r and `2r` respectively. If stream line flow is maintained and pressure difference across first and second capillary tubes are `P_(1)` and `P_(2)` respectively then find the ratio `(P_(1))/(P_(2))`.

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.

L,(L)/(2) and (L)/(3) are connected in series. Their radii are r, (r)/(2) and (r)/(3) respectively. Then, if stream-line flow is to be maintained and the pressure across the first capillary is P, then:

L,(L)/(2) and (L)/(3) are connected in series. Their radii are r, (r)/(2) and (r)/(3) respectively. Then, if stream-line flow is to be maintained and the pressure across the first capillary is P, then:

Three capillaries of length L, (L)/(2) and (L)/(3) are connected in a series. Their radii are r, (r)/(2) and (r)/(3) respectively. If a streamlined flow is to be maintained and pressure difference across the first capillary is rho , then the pressure difference across the second capillary will be
