Spec Sheet Description
Particle Drag Coefficients
The device is designed to show the relationship between the drag coefficients of falling spheres and their Reynolds’ number value.
The spheres fall through a number of different liquids contained in 2 vertical glass tubes. As the spheres have a projected area of only 1% max of the tube cross-section, wall effect is reduced to a minimum.
Timing the passage of the particle between two marks on the walls of the glass tubes allows measuring their rate of fall. Different particles covering a range of sizes and densities are supplied.
Training Program:
- Measurement of drag coefficients of spheres as a function of their Reynolds’ number
- Effect of particle shape on rate of fall and on drag coefficient
- Effects of boundary layer separation on motion of spheres
Supplied with Theoretical – Experiement Handbook
