361368 Two tubes of radii \(r_{1}\) and \(r_{2}\) and lengths \(l_{1}\) and \(l_{2}\), respectively, are connected in series and a liquid flows through each of them in stream line conditions. \(P_{1}\) and \(P_{2}\) are pressure differences across the two tubes.

361371 Two capillary tubes of the same length but different radii \(r_{1}\) and \(r_{2}\) are fitted in parallel to the bottom of a vessel. The pressure head is \(p\). What should be the radius of a single tube that can replace the two tubes so that the rate of flow is same as before
361372 A volume \(V\) of viscous liquid flows per unit time due to a pressure head \(\Delta P\) along a pipe of diameter \(D\) and length \(L\). Instead of this pipe a set of 4 pipes each of diameter \(\dfrac{D}{2}\) and length \(2 L\) is connected to the same pressure head \(\Delta P\). Now, the volume of the liquid flowing per unit time is
