Halliday, Resnick & Walker — Fluids: Problem 5

5 The maximum depth \(d_{max}\) 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 0.050 atm. What is the difference in \(d_{max}\) for fresh water and the water of the Dead Sea (the saltiest natural water in the world, with a density of \(1.5 \times 10^3 \text{ kg/m}^3\))?
