1. The problem statement, all variables and given/known data In scuba diving, a regulator is used so that the pressure of the air the diver breathes is close to that of the ambient water. A reckless swimmer decides to use a hose sticking out of the surface to breathe underwater while diving in a lake. When the air pressure in the lungs is at a pressure of around 0.130 atm below the ambient pressure, lung injury may occur. Find the depth at which the swimmer would experience such a pressure differential. 2. Relevant equations p = po +pgd 3. The attempt at a solution p = po + pgd -po/pg = d -101300 / ((0.13 * 101300) * 9.8) = 0.78 What am I doing wrong??
