I think Vance is correct, around 65 pounds displacement. Too lazy
to do it in metric, but English units are:<br>
<br>
3.14 x (5x5) x 14 = 1099.55 cubic inches<br>
<br>
1728 cubic inches per cubic foot<br>
1099.55 / 1728 = .63 cubic feet<br>
<br>
1 cubic foot seawater = 64 pounds (ok,63.something, but 64 is
close enough)<br>
.63 * 64 = 40 pounds displacement<br>
<br>
So there's 40 pounds displacement just for the cylinder. Add in
your two end caps and you get close to 65 pounds total.<br>

<div>15 litres total displacement. So that's 15 kg</div>
<div> </div>
<div>15kg = 33lb </div>
<div> </div>
<div>Not taking into account the weight of the tank itself.</div>
