Confirm wing lift?

[WeldonDowd]

If he uses the same technique to test this new wings lift then he will still think he has a 45 lb wing. DSS got a sale out of all this though.

It never fails to amaze me how tortured simple concepts can get.

Wing lift equals the weight of the water placed in the wing during the test method I have repeated described.

The delta, not the weight of the entire rig + the water.

You seem to think the people asking the question are "torturing" the concept or otherwise misunderstanding you. Your point is crystal clear. It's just not what the OP said he did.

If my point was clear to the OP he would *NOT* have done what he claimed.

(I'm still not certain exactly what he did do)

He may be guilty of nothing more than inattentive post-writing. Who among us can cast the first stone on that offense?

It's of no benefit to anyone here when these concepts get tangled.

Ugg, I hope I did not screw it up. I have it written on a piece of paper somewhere, I will try to find it. But if I was wrong (not ready to admit it just yet.....) I would imagine that instead of just saying to return it, they might have asked a few questions on how I came to my results and determine what the problems/concerns were.

And if the tags on the wing and box said 35 instead of 40, I would have assumed it was a 35 and been diving it for a few weeks by now.

Ah, okay, Halocline, I see what you were saying now. Sorry for doubting you. (And thanks RJP for re-posting the earlier quote).

Ok I found the magic paper. I hate to admit how much I weigh, but here it goes....

Me: 261.4
Me+Empty BP/W 272.2
Me+BP/W+Water 316.6


So 272.2-261.4=10.8 (Me+BP/w - ME) = 10.8 Empty BP/W

Now Me+bp/w+water = 316.6

So if I subtract (Me + Empty bp/w) 272.2 from the (Me+bp/w+water) 316.6 I get 44.4

316.6 - 272.2 = 44.4

Looking at the original post when I say it weighed 44.4 lbs I was talking about the wing only, not the wing and the plate/harness. I threw in the dry/empty weight (10.8) I guess as just a reference?? I have no idea, but it must have made sense at the time on how I explained everything.

But I can see how Halocline and RJP explained it with the information they had because I did not fully explain the process of how I achieved the numbers.

Sorry to cause a ruckus, but it is nice to know someone is paying attention and keeping me honest.

You know you could have just said that you weighed 161.4 lbs and we all would have believed it!


Why not just fill the wing while it's on a tank, then drain it into a bucket and weigh the water, or even just measure volume? We all know how much a liter of water weighs...
