When a fluid is contained within a pipe or capillary tube, is it acted on by the largest force of friction near the walls or in the center of the tube diameter? Explain
Homework Answers
Ans.
When a fluid is contained within a pipe or capillary tube, it is acted on by the largest force of friction near the walls.
The inner surface of the pipe or capillary tube offers some friction. As the layers of the fluid from the walls increases, the friction experienced decreases. So, the largest friction is experienced near the walls.

An experimental apparatus delivers a viscous fluid through a capillary tube 10 cm long with a bore diameter of 1 mm. The tube is broken, but tubing of bore diameter 2 mm is all that is available. What should be the length of the new tube in cm so that the experiment is otherwise unchanged, i.e., so that the volume flow rate remains as before?

4. An incompressible fluid with viscosity u and density p was contained in pipe of length L and radius R. Initially the fluid is in rest. At t=0, a pressure difference of AP is applied across the pipe length which induces the fluid flow in axial direction (V2) Only varies with time (t) and pipe radius (r). There is no effect of gravity. To describe the fluid flow characteristics, after the pressure gradient is applied, answer the following questions: a)...

A magnet is dropped down a copper pipe. In the walls of the tube, there is an induced voltage as the magnet falls. Many field lines that are appear where where there originally were no field lines. When there is a change in flux, there is an induced current in the conductor that generates the magnetic field opposing the change. Some opposing force arises in the pipe that pushes up on the magnet as its going down, therefore making it...
