|I wanted to convert my findings to one of the traditional
units for viscosity, either centipoises or Pascal-seconds or
Slugs/foot second, or degrees
MacMichael so I found this formula to help.
It is a modified configuration of Stoke's Law.
|The first viscosity I tried calculating was that of water.
I plugged my values for water in, including the density of the water, the density and the speed of the ball.
|A little math...|
|I converted the disparate units to centimeters, grams and seconds.|
|I cancelled out some centimeters on the top.|
|Close to an answer.
I got stuck at this point and consulted a real scientist & cockeyed.com supporter, John O'Meara at the Center for Astrophysics & Space Sciences at UCSD.
He was operating without the benefit of Goldschlager, but coaxed me forward in my calculations.
|Clearing more units.|
|I arrived triumphantly at an answer! 1.095 g/cm-s or 0.1
kg/m-s. This is the correct format for an answer, but the well-documented
viscosity of water is actually .001 kg/m-s.
John arrived at the same numbers and was as perplexed as I am.
I seem to be off by a factor of 100.
I used this technique to calculate the incorrect viscosity for the eleven other liquids too.
