The following formula (In Laymen's Term's) is used in the
process for calculating part
of the Coast Guard approval process for minimum buoyancy!
If a man weighs 200 pounds on land, he only weighs 10
pounds in the water.
80% of the human body is water. Water in the body has
no weight in the water.
200 pounds x 80% = 160 pounds. So 200 pounds 160 pounds =
40 pounds.
The human body is 15% fat, fat is lighter than water.
200 pounds x 15% = 30 pounds. So 40 pounds 30 pounds = 10
pounds.
A 200 pound person only weighs 10 pounds in the water.
So
.If a man weighs 350 pounds on land, he only weighs
17.5 pounds in the water.
350 x 80% = 280 pounds. So 350 pounds 280 pounds = 70
pounds.
350 pounds x 15% = 52.5 pounds. So 70 pounds 52.5 pounds
= 17.5 pounds.
A 350 pound person weighs 17.5 pounds in the water.
This 50" Rescue Tube equals to 44 Lbs of Buoyancy.
