(10 pts) A scuba diver swimming at a depth of 10 m is breathing air at pressurized to P- 23 atn scuba air tank regulator increases pressure at a rate of 1 atm per 10 m depth.) If the diver ascends qu surface where the pressure is Po 1 atm, the high pressure nitrogen in the blood will tend to form b the surface tension of blood-nitrogen interface is 0.058 N/m, what size diameter (in millimeters) bu form based on the maximum pressure difference experienced by the diver?

Explanation / Answer

1) Pressure difference experienced = 23 - 1 = 22 atm or 2229.15 kPa

     Pressure created due to bubble = 0.058 / d

     0.058 / d = 2229.15 * 10^3

     d = 2.6 * 10^-5 mm
