FREE & FORCED VORTEX APPARATUS

Product Description

The free vortex lab set up comprises of a circular transparent cylindrical tank made of clear acrylic in which four jets are placed along the circumference of the cylinder at its bottom end, these jets help in the formation of free vortex. Theoretically it is presumed that the torque exerted by these jets is negligible. A pointer is placed in transverse direction, horizontally & vertically across full diameter of the vessel so as to measure the water surface profile. Both the axis have graduations so that exact position of the pointer can be known. This experimental procedure involves measurement of the resulting free surface that is calculated by the variation of the sum of the pressure head and datum head. A drain pipe is provided to drain the vessel when not in use.

The forced vortex experimental set up is an arrangement of a circular transparent cylindrical tank in which a plate is rotated with the help of a variable speed motor so that as a result the cylinder attached to the plate rotates on its vertical axis with the help of a V belt and hence forced vortex is formed. An upper probe is placed in a transverse horizontally & vertically across full diameter of the vessel so that water surface profile can be measured. Both axis contain graduations so that exact position of the probe can be recorded. This experimental procedure involves measurement of the resulting free surface that is calculated by the variation of the sum of the pressure head and datum head. A drain pipe is provided to drain the vessel when not in use.

SCOPE OF STUDY:

  • To plot the surface profile of a forced vortex by measurement of the surface profile coordinates.
  • To plot the surface profile of a free vortex by measurement of the surface profile coordinates.
