Fat?

[afdgf]

I have a stranger-than-normal question. If a diver needs, for example, 20 lbs. of lead for good buoyancy and has liposuction during which 4 lbs. of fat is removed, then how much less lead would the diver need after the liposucton, ceteris paribus? Is the relationship 1:1 2:1 or what? Does anyone know?
TIA

I sure don't know but please tell us when you find out!

Specific gravity of fat is about 0.91
Specific gravity of seawater is about 1.025
Specific gravity of lead is about 11.35
So in seawater you should be able to shed a pound of lead for every 10 pounds (approximately) of fat that is liposuctioned .

How about the water displacement change?

That would be covered in the specific gravity difference between fat and seawater. I think I'll just carry the extra lead.

On the live-abord boats I have been on, you might make up the liposuction fat deficit pretty quickly.

neat.

so is the equation (pounds lost) / 11.35?

or (pounds lost * .115) * 11.35?
