Question

The maximum depth dmax that a diver can snorkel is set by the density of the water and the fact that human lungs can function against a maximum pressure difference (between inside and outside the chest cavity) of 0.038 atm.What is the difference in dmax for fresh water and the water of the DeadSea (the saltiest natural water in the world, with a density of 1.40× 103 kg/m^3)? Number Enter your answer in accordance to the question statement

Answer 1

Given

density of sea water

Pressure limit = 0.038 atm

Conversion

1atm = 101.325kpa

0.038 atm = 3.85 kpa

Formula

where P = pressure, g = acceleration due to gravity, = density

For the fresh water.

for the dead sea water

dofference between the hight is
