`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

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

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.

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)) .

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:

Three capillaries of lengths l_(1),l_(2) and l_(3) and radii r_(1),r_(2) and r_(3) respectively are joined in series. If p is pressure difference across the combination of capallaries, what will be the volume of liquid flowing per second?
