Fluid Circulation In A Smooth Pipe


In this experiment, three varying flow meters are used to alter the flowrate. Changes in pressure drop due to the change in flowrate happen to be then noticed from the 3 pressure gauges that can assess pressure for different range and recorded. The move from laminar flow to turbulent movement is seen from the results noted, but it is observed even more clearly through the water-soluble dye experiment that was completed by the demonstrator. Laminar movement turns to become turbulent if the Reynolds Quantity goes over a certain value, around 2k.


To think about how the pressure drop changes when the normal velocity is usually altered in a circular water pipe and to story a chart of Friction Factor vs . Reynolds Amount. Another target is to analyze the shift from laminar flow to turbulent stream.

A chart of log - journal plot of f vs . Re is plotted, and a straight brand of best fit throughout the data factors for laminar flow is definitely drawn:

To estimate the incline of the best suit line by Figure 2, two points happen to be selected: (600, 0. 02) and (200, 0. 07) slope=log(0. 02)-logвЃЎ(0. 07)log600-logвЃЎ(200)

slope=-1. 14

Theoretically, in the alisar flow plan for pipe flow,




logf=-logRe+1. 2

So , we expect the importance of the incline to be -1. In Figure2, the incline found can be -1. 13, which is close to -1. The two values accept each other. With the maximum flowrate, Q = 1600L/hr = 4. forty-four x 10-4 m3/s
