FM 14 FREE AND FORCE VORTEX APPARATUS

The experimental set up consists of two circular transparent cylindrical tanks fitted on plate. One Tank is fitted with four circumferential jets have been placed along the circumference of the cylinder near its bottom. A replaceable orifice is kept at the bottom plate at drain & to get different conditions. Flow of water from sump tank & supply pump when allowed to enter the cylinder exiting out through the drain orifice at bottom helps in the formation of free vortex. (It is assumed that the torque exerted by these jets is negligible). The other circular transparent cylindrical tank can be rotated with the help of a variable speed motor so that the cylinder rotates about its vertical axis. Add water from top of tank to form the forced vortex. A pointer gauge is provided to measure the profile of vortex formation. Conditions were allowed to steady state and the depth of flow at any particular point was observed not to change over a period of time. The system is closed circuit type contains their sump tank, collecting tank, supply tank, pump, motor, pipe line etc. The tanks are duly painted to protect from rust and corrosion.

• • To plot the surface profile of a free and forced vortex by measurement of the surface profile coordinates and to show that total energy is constant throughout vortex.
