Chapter 3, Problem 10P
A diver's watch resists an absolute pressure of 5.5 bar. At an ocean having density of 1025 kg/m3 and exposing an atmospheric pressure of 1 bar, what depth can maximally the diver dive to prevent water inlet into his watch? 1 bar = 105 Pa and g = 9.81m/s3.

If a scuba diver descends too quickly into the sea, the internal pressure on each eardrum remains at atmospheric pressure, while the external pressure increases due to the increased water depth. At sufficient depths, the difference between the external and internal pressures can rupture an eardrum. Eardrums can rupture when the pressure difference is as little as 35 kPa. What is the depth at which this pressure difference could occur? The density of seawater is 1025 kg/m3.

A cylindrical tank is fully filled with water . In order to increase the flow from the tank, an additional pressure is applied to the water surface by a compressor. For P0 = 0, P0 = 5 bar, and P0 = 10 bar, calculate the hydrostatic force on the surface A exerted by water.
A barometer reads 80 cm Hg and a pressure gage attached to a tank reads 40 cm of Hg. Determine the absolute pressure in the tank.
