Product Code : SCL-CELE-14009
This apparatus is a self-contained unit designed to visually
demonstrate and quantitatively measure the surface profile of a forced
vortex (or rigid-body rotation). This type of flow is created when a fluid
is rotated by an external torque, such as an impeller or rotating container.
1. Key Components and Design
The setup uses a rotating cylinder and a movable probe for
accurate measurement of the water surface.
- Vortex
Vessel (Cylinder): The fluid is contained in a transparent
cylinder.
- Material: Acrylic
(transparent for observation).
- Dimensions:
Diameter 200 mm (approx.), Height 200 mm (approx.).
- Rotation
Mechanism: A circular transparent plate at the
bottom of the cylinder is rotated about its vertical axis using a Variable
Speed, DC Motor.
- The
motor uses a V belt connection.
- The
rotation of the plate imparts torque to the water, forming the forced
vortex.
- Measurement
Probe: An upper probe is provided.
- Function: This
probe can be traversed horizontally and vertically across the full
diameter of the vessel.
- Purpose: To
precisely measure the shape and height of the paraboloid water surface
profile formed by the vortex.
2. Control and Operation
The apparatus includes a control panel for regulating the
rotational speed.
- Motor: Variable
Speed, DC Motor (Compatible capacity).
- Control
Panel: Comprises a Speed Control Unit, standard On/Off
Switch, and Mains Indicator.
3. Purpose and Experiments
The primary experiment is the verification of the theoretical
shape of a forced vortex.
- Vortex
Profile Measurement: Measure the relationship between the radius r
and the water surface height z at various points.
- Theoretical
Verification: Compare the measured surface profile with the
theoretical equation for a forced vortex, which predicts a paraboloid
shape propto r2.
