Problem 17E

BIO There is a maximum depth at which a diver can breathe through a snorkel tube (?Fig. E12.17?) because as the depth increases, so does the pressure difference, which tends to collapse the diver’s lungs. Since the snorkel connects the air in the lungs to the atmosphere at the surface, the pressure inside the lungs is atmospheric pressure. What is the external– internal pressure difference when the diver’s lungs are at a depth of 6.1 m (about 20 ft)? Assume that the diver is in fresh-water. (A scuba diver breathing from com-pressed air tanks can operate at greater depths than can a snorkeler, since the pressure of the air inside the scuba diver’s lungs increases to match the external pressure of the water.)

Step-by-Step Solution:

Solution 17E Step 1 of 3: The absolute pressure P(d) at a depth d inside a fluid with density , is greater than the pressure at the surface(P 0 by an amount gd. Also the pressure is same at any two points at the same level in the fluid, irrespective of the shape of the container. External Absolute Pressure at depth d, P(d) = P 0gd……………...1 Similarly the pressure of the lungs is same as that of the surface pressure(atmospheric pressure) P = P ……………….2 lungs 0 Step 2 of 3: Given data, Depth d=6.1 m 3 Density of fresh water, = 1000 kg/m 2 Acceleration due to gravity, g= 9.8m/s To find, The external and internal pressure difference(gauge pressure),P = P(d)-P lungs=
