I've been teaching ME students the use of Raimondi & Boyd's Sommerfeld number -> dimensionless variable charts for years. The method is in every machine design text, but I am curious as to if anyone actually uses it in practice. It doesn't appear to have changed much since 1958 (not that that's a bad thing). I would appreciate hearing from folks who use it, and also from current alternative methods of journal design - even if it is commercial or proprietary software.
 
I use Raimondi & Boyd data all the time. Works fine.
 
Could you share (roughly) what range of speeds, bores, loads, lubricants, and/or temperatures that you work with? Thanks.
