Formula to Determine 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
200 pounds – 160 pounds = 40 pounds
The human body is 15% fat, fat is lighter than water.
200 pounds x 15% = 30 pounds
40 pounds – 30 pounds = 10 pounds
A 200 pound person only weighs 10 pounds in the water.
A U.S.C.G. approved Type V vest is mandated to have 17.5 pounds of buoyancy.
If a man weighs 350 pounds on land, he only weighs:
80% of the human body is water. Water in the body has no weight in the water.
350 x 80% = 280 pounds
350 pounds – 280 pounds = 70 pounds
The human body is 15% fat, fat is lighter than water.
350 pounds x 15% = 52.5 pounds
70 pounds – 52.5 pounds = 17.5 pounds
A 350 pound person weighs 17.5 pounds in the water.
