Fat Sac Tube 20X50

Recommended Posts

chrisallenhogs

Does anyone know how much weight the large tube holds? I believe it is 50" x 20" if my measurements are correct. I bought it in '05. Needing to know how much weight it holds, I thought it was 800lbs to 1000lbs.

If it's a Pro X Series Tube Sac then it's 62x16x20 and holds 370lbs.

its not the pro x series, its the older model. It is the round tube not the rectangle tube.

How long is it?

If you have all three dimensions you can figure out the volume. I think this is the right formula.

The formula is:

V = 3.142 x R x R x H x 7.48

Where:

V = tank volume in gallons

R = tank radius in feet

H = tank height in feet

It is a complete circle so I would geuss blown up on the floor it would be 20" high, 20" wide, and 50" long. I don't knwo all the radius and diameter formulas. Maybe someone smarter than me can figure it out.

all right my brain is hurting trying to bring back this old math.

Figure out the cubic area first

Area=LxWxH

20x20x50=20,000 Cubic inches

1 cubic inch = .000433 gal.

fat sac capacity .00433 x 20,000 = 86.6 gal

1 gal of water weighs 8.6 lbs

86.6 gal x 8.6 lbs = 744.76 total lbs.

Your math is for a cube however, and the fat sac is a cylinder!

Alright 20" diameter fat sack, 50" long

specific weight of freshwater = 62.4 lbf/ft^3

volume of fat sack = pi*R^2*L (r=radius, L=length both in feet)

weight = specific weight * volume

weight = 62.4[pi*(10/12)^2*(50/12)] (divide by 12 to go from inches to feet)

weight = 567.23 lbf

Guys, go to wakeside.com Skylon tube 50 x 20 is 580lbs fill capacity per Skylon.

For a 20" diameter by 50" cylinder the volume is 15,700 cubic inches which equals 68 gallons which weighs 585lbs, so guesstimate in the real world about 500lbs

I didn't mean to cause so much confusion, anyway I think I am going to sell this particular sac. Just wanted a idea of the weight.

V=

R=0.83 ft

H=4.17 ft

V=3.142x0.83x0.83x4.17x7.48

V=67.515gallons

67.515x 8.6= 580lbs

1 gallon = 8.337 pounds in my fluid mechanics book....
