Suppose we have a garden hose laid on a concrete floor. This garden hose is made out of rubber and is sealed on both sides. It is completely filled with water with no air bubbles whatsoever.
The outside, inside diameter and length of the hose are known and we assume (for sake of simplicity) that the bulk modulus of water is infinite and the rubber hose doesn't expand or contract under pressure.
Now let's say 70Kg person stands on the hose - what will be the pressure inside the hose?
P.S. This is not a homework - I am puzzled by what happens with the pressure inside the hose as it is a part of thought experiment of mine...
