[QUOTE="BigBboy25, post: 802710, member: 18342"] Well, according to fluid mechanics, when fluid velocity increases, pressure decreases. (Bernoulli's equation shows this very clearly.) This is what allows air planes to fly (at a very basic level!). The wings are designed so that the air is moving faster on top of the wing than on the bottom. this causes there to be lower pressure on top of the wing and higher pressure below the wing, thus generating lift. Keep in mind that the top of the wing and bottom of the wing are roughly at the same elevation but the pressures are very different on each side of the wing. . . just something to think about. As to the pressure changes experienced on the Kestral, my guess is the 'burbles' are lower pressure areas. So if you're on the right spot on the mountain where one of those is occurring, you may see a small pressure change on the kestrel. However, it is nearly impossible to say how big that 'burble" area is, so I do not know if you would need to account for it for a 1500-2000 yard shot. If you only shoot through 200 yards of the 'burble' area, then the remaining 1,300 yards are in relatively static air, I'm not sure you'd need to account for the pressure change in the 'burble'. This is just my hypothesis however. Using what I know of fluid mechanics and trying to piece things together. I think the best thing to do would go out there and sling some lead and see what happens. Very interesting stuff! [/QUOTE]
