If you are searching for the high quality Free and Forced Vortex Apparatus, then you can contact us. Our company is identified as one of the reliable Manufacturers, Exporters and Suppliers of Laboratory Apparatus in India. This apparatus consist of a circular transparent cylindrical tank where four circumferential jets are installed along with the circumference of the cylinder which helps in the formation of free vortex. Working of Free and Forced Vortex Apparatus : It is assumed that the torque exerted by these jets is negligible. The Orifice is reducing bush so that a reduced diameter can be investigated. The plate can also be rotated with the help of a variable speed motor so that the cylinder rotates about its vertical Axis with the help of a V belt and forced vortex is formed. Conditions wear allowed to steady state and the depth of flow at any particular point was observed not to change over a period of time. The experimental procedure involves measurement of resulting free surface that represents the variation of the sum of the pressure and datum head.
