Again, 0.5% differences...maybe.
After running a quick CFD comparison, I see no appreciable difference. |

If boat A is 2.5" shorter than boat B and they're traveling in exactly opposite directions on a head-on collision course while on a section of the Mississippi River with a 10 mph current and both of their GPS's indicate 100 mph, what is their closing speed with regards to one another? What would each water pitot speedometer read. assuming they're accurate? :evilb: |
