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 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 two ends of the first capillary tube. 38.cm of Hg

Two capillary tubes of same length each of 50 cm but of different radii 4 mm and 2mm are connected in series. When water flows, the pressure, difference between the ends of the first tube is

Two capillary tubes of length 15 cm and 5 cm and radii 0.06 cmand 0.02 cm respectively are connected in series. If the pressure difference across the end faces is equal to pressure of 15 cm high water column, then find the pressure difference across the (i) first tube and (ii) second tube.

Two capillaries of same length and radii in the ratio 1 : 2 are connected in series. A liquid flows through them in streamlined condition. If the pressure across the two extreme ends of the combination is 1 m of water, the pressure difference across first capillary is
