Main Question or Discussion Point
I want to test several different fluids on an inclined planes and figure out which one is the most slippery. What would be the most scientifically sound way to measure this?
The "standard" model is the Reynolds lubrication equation. http://www2.imperial.ac.uk/~ajm8/M3A10/lub.pdf (or google for other references).Better yet, develop a fluid mechanics lubrication model to calculate in advance what to expect from the inclined plane tests.
