About This Product
Each run drops one particle into a tube and times it between the marks to give its rate of fall, from which the drag coefficient is worked out. Repeating this with different particles and liquids shows how size, density and viscosity affect drag.
Frequently Asked Questions
How is the rate of fall measured?
By timing the passage of a single particle between two marks on the wall of the glass tube.
Do the tubes need draining to recover particles?
No. A valve system at the bottom of each tube lets particles be removed with the minimum loss of liquid.
What does the user provide?
Liquids of different viscosity, a 100 watt, 220 V single-phase supply and a floor area of 0.75 m x 1.5 m.
