Pool weight?

Question

How much weight do we "lose" in the water?
Ex: if someone weighs 160lb, how much do they weigh in the water?

Answer 1

hmmm, if someone 'weighs' 160 lbs on dry land,
then usually they would 'weigh' maybe "-10 lbs"
in the water, since most people float ... with the
amount of flesh 'above waterline' kinda small ...
(that amount constituting 10 lbs as a guess)

if a person is very muscular 160 lbs, they might
'weigh' +5 lbs in the water, since they might not
float, since muscle mass is denser than fat.


in line with the Archimedes observation, measure the
displaced water which spills out of the "full to the rim"
pool, and called this "X" ...

now pull your body all the way under the water and call
the "extra" water displaced "Y"

how much you 'weigh' equals "minus Y"

*********

if very muscular, different steps, using a "floatation
pan" and call the "floating on top" displaced water "X"

.. get out, refill and then sink to the bottom and call it "Y"

weight = 'X-Y'

Answer 2

According to Archimedes Principle, the decrease in weight will be equal to the weight of water the body displaces.

A tub is filled to the brim, and the 160 lb person gently eases into the tub such that the overflow is collected and weighed. If that overflow is 60 lb, then the person weighs 100 lb. in the water.

Answer 3

THE FORCE of gravity is relatively constant. You will still weigh 160 lbs. however, your weight is displaced by the water. Vessels ( boats and the like ) are rated in classes of displacement. Gravity is relative to your position in the universe. You are on earth. Were you on the earths moon, your weight would be 15 per cent because of the associated mass of the moon.
