Vanair Enterprises: The Kappa System Viscosity for Synthetic Oils - Issue 20110714
http://www.vanairent.com/2011/07/kappa-system-viscosity-for-synthetic.html
Saturday, July 16, 2011. The Kappa System Viscosity for Synthetic Oils - Issue 20110714. Vanair Enterprises again wishes to thank Markus Raabe of MESYS in Switzerland ( www.mesys.ch. Which writes bearing design programs and other machine design programs. He has supplied the missing formulas that allow a user of the Kappa (k) oil film system* to transpose the mineral oil system values to synthetic or other oil film values. In order to do this, the following equations were used to generate the end formula.
