If l is length of the tube and r is the radius of the tube, then the rate of volume flow of a liquid is maximum for the following measurements. Under the same pressure difference.

The rate of steady volume flow of water through a capilary tube of length and radius r under a pressure difference of Pis 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 under same pressure difference across the combination is

A liquid is flowing through a narrow tube. The coefficient of viscosity of liquid is 0.1308 poise. The length and inner radius of tube are 50 cm and 1 mm respectively. The rate of flow of liquid is 360(cm^(3))/(min) . Find the pressure difference between ends of tube.

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 )

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 )

The rate of steady volume flow of water through of capillary tube of length 1 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)
