Under a constant pressure head, the rate of streamlined volume flow of a liquid through a capillary tube is V. if the length of the capillary tube is double and diameter of the bore is halved, find the rate of flow of the liquid through the capillary tube.

The rate of flow of the liquid through the tube of length l and radius r, connected across a perssure haed h be V. If two tubes of the same length but of radius r and r//2 are connected in series, across the same pressure head h, find the rate of flow of liquid through the combination. If both the tubes are connected inparallel to the same pressure head, then find the rate of flow of liquid through the combination.
