Product Description
Forced Vortex Flow is an example of rotational flow and can be generated by rotating a cylinder containing a fluid about its axis or by rotating a paddle in a large volume of fluid. Under steady conditions, each particle will move with the same angular velocity and there will not be any relative motion between fluid particles. Streamlines for such a flow will be concentric circles and the total energy is constant along a streamline but varies from one streamline to another.
Scope Of Experimentations:
Fill the cylinder with water to about one half of its height
Rotate the cylinder with constant and reasonably fast speed
The free surface of the water takes the form of a parabolic profile
Measure the speed of rotation
When conditions become steady, take the surface profile readings by traversing the Pitot-static tube, immersed just beneath the water surface along a radial line The surface elevation at r0 is taken as the datum for all these readings
Now for the second run, speed from motor has been changed and again at steady state, take the surface profile readings
Utilities Required:
Power supply: Single Phase, 220 volts, 50 Hz, 5 Amp with earth
Water Supply
Drain
Technical Details:
Do not run the pump at low voltage i.e. less than 180 Volts
Always keep apparatus free from dust
To prevent clogging of moving parts, rum pump at least once in a fortnight
Frequently Grease/Oil the rotating parts, once in three months
Always Use Clean Water
If the Apparatus is not in use for more than one month, drain the apparatus completely, and fill pump with cutting oil
