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?

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.

Two wires of equal diameters of resistivies rho_(1) and rho_(2) and lengths l and l respectively are joined in series. The equivalent resistivity of the combination is

We have two (narrow) capillary tubes T and T . Their lengths are l and l and radii of cross-section are r and r respectively. The rate of flow of water under a pressure difference P through tube T is 8 cm 3// sec . If l = 2l and r = r what will be the rate of flow when the two tubes are connected in series and pressure difference across the combinatin is same as before (= P)

Two copper wire of length l and 2l have radii, r and 2r respectively. What si the ratio of their specific resistance.?

Two capillary tubes of equal length and inner radii 2r and 4r respectively are added in series and a liquid flows through it. If the pressure difference between the ends of the whole system is 8.5 cm of mercury, find the pressure difference between the ends of the first capillary tube.

Two wires of equal diameters, of resistivities rho_(1) and rho_(2) and length l_(1) and l_(2) , respectively of the combination is

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)) .
