VISCOSITY AND PARTICLE DRAG

Self standing simple falling sphere viscometer, that demonstrates the drag coefficient of different sized particles (spheres) and the viscosity of liquids.

The Viscosity and Particle Drag apparatus is a simple falling-sphere viscometer. The self-standing unit holds two glass tubes filled with the test fluids, for comparisons and to minimise draining and refilling of the fluids after experimentation. The back plate has a low-voltage backlight so students can easily see the test spheres through the fluid. Learn about VISCOSITY AND PARTICLE DRAG manufacturers for optimal educational outcomes.. Students fill the two tubes with their chosen test fluid, then select a sphere of the correct density and size for the fluid. They drop the sphere into the test fluid at the top of the glass tube.

When the test sphere reaches the bottom of the tube, it enters a valve that the students turns, dropping the sphere into a collection vial for recovery.

The valve system minimises the fluid loss from the tube and helps when draining the tube after the tests are complete.
