What's a good estimate for these constants? .85 for both of them? |
In my experience you can generally just use one number for speed loss for the whole system regardless of gear ratio. "Speed loss" is really just the lowered free speed of the system caused by the negligible loading of by overcoming kinetic friction. For well greased gearboxes it shouldn't change *too* much.
I've always used 81% as a "speed loss constant", allegedly the result of experimental data collected by 229, but I wouldn't be surprised if it was just some arbitrary number somebody came up with.
