Blue?

What are we talking about?

How much weight will a 42" cylinder that is 5' long float before it sinks below the surface of the water.

Posted: **Mon Nov 11, 2013 6:49 pm**

Assuming it's a cylinder, 51.5lbs give or take.

Source: Google and doing some fucking math.

Assuming the barrel has zero weight it would take.~ 866 pounds to sink it.

300.66 #s

I may have done that wrong. :lol:

42"/12/2(pi^2)=17.27
17.27X5=86.36cubic feet
1 cubic foot floats approx 62.4lbs
86.36X62.4=5389lbs

Will float 5389lbs minus the weight of the tube before it sinks.

A cubic foot if water weighs 62.4 pounds. The radius is 1.666'
Square that.
Then times it by 5'

A=pi x r^2

It ain't 866. Lol
2720 pounds. I forgot to throw the pie in. D'oh.

Nope. My answer is close to right. I'd say about 5000lbs to stay on the safe side.

Posted: **Mon Nov 11, 2013 7:02 pm**

Ok. Scratch that again. It's 3000lbs

2 oz of buckshot

What is the cylinder made of and is it hollow? Or is it a cylinder of solid steel? Is this a trick question? Will this be on the final?

$1 Bob

Thanks for the help. So it is about 600 pounds per foot.

How many cubic feet per foot?

Posted: **Mon Nov 11, 2013 7:29 pm**

Yeah, how many holes?

It's plastic culvert pipe. I'm trying to figure out how much concrete it's going to take to sink it.

It will be standing on it's end, the bottom filled with concrete and will only have a few inches sticking up above the water. Similar to a small pit blind in a field but it will be in the middle of open water.

Sorry to bust your bubble but aren't sink boxes banned federally?

Posted: **Mon Nov 11, 2013 7:36 pm**

You do know sink boxes are illegal in the states don't you?

Oh, I get it. Probably closer to 500 once you figure the weight of whatever your talking about.

About 9.5 cubic feet in every foot of length for the tube.

Make sure you're not standing in it when they pour the concrete. :lol:

You putting that thing in Pamlico sound?

Not accounting for the weight of the tube itself
