Viscosity And Particle Drag

Viscosity And Particle Drag

•    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 minismise draining and refilling of the fluids after experimentation.
•    They drop the sphere into the test fluid at the top of the glass tube.
•    They then use a stopwatch to measure the time taken for the sphere to fall a set distance down the tube.
•    The back plate has a low-voltage backlight so students can easily see the test spheres through the fluid.
•    Students fill the two tubes with their chosen test fluid, then select a sphere of the correct density and size for the fluid.
•    The valve system minimises the fluid loss from the tube and helps when draining the tube after the tests are complete.
•    The shapes must fit through the valve at the base.
•    Suitable test fluids include water, thin machine oil, castor oil and motor oil.
