human lung can withstand an inside/outside difference of about .06 atm. if a diver is using a snorkel to breathe, how far below the water surface can he get before he is risking lung damage? pressure of outside is the water pressure at that depth, while pressure inside is the pressure of the air being breathed.
this is what i have...
.06 = 1.01e5 / (1.01e5 + 1000(9.8)(h)
the above calc comes from equation P= Po +density(g)(h)...1000 is the density of water given to us, and 1.01e5 is atmospheric pressure,,,,, by solving for h i get an answer of 161.45 m...and not suprisingly I am way off, the correct answer is .62m where did i go wrong here
