The rate of steady volume flow of water through a capillary tube of length ‘ l ‘ and radius ‘ r ‘ under a pressure difference of P is V . This tube is connected with another tube of the same length but half the radius in series. Then the rate of steady volume flow through them is (The pressure difference across the combination is P )

We have two (narrow) capillary tubes T1 and T2 . Their lengths are l1 and l2 and radii of cross-section are r1 and r2 respectively. The rate of flow of water under a pressure difference P through tube T1 is 8cm^3/sec. If l1=2l2 and r1=r2 what will be the rate of flow when the two tubes are connected in series and pressure difference across the combination is same as before (=P)
