Water of density `p` flows with a linear speed `v` through a horizontal rubber tube having the form of a ring of radius `R`. If the diameter of the tube is `d(ltlt R)`, find the tension in the rubber tube.

When a liquid moves steadily under some pressure through a horizontal tube, it moves in the form of cylindrical layers coaxial to the ends of the tube. The velocity of different layers is different. The velocity of the layer is maximum along the axis of the tube and it decreases as one moves towards the walls of the tube. According to Poiseuille, the rate of flow of liquid through a horizontal capillary tube varies as the relation V alpha (pr^(4))/(eta l) where l and r are the length and radius of the tube and p is the pressure different between the ends of the tube and is the constant of proportionality. When two capillary tubes through which the liquid is flowing are joined in series then the equivalent liquid resistance is

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 value of end correction for the pipe open at both the ends is a (If the d is the inner diameter of the tube and r is the radius of the tube .)
