- 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 = 9.81 m/s2.If air had a constant specific weight of 0.076pound pet cubic feet and were incompressible. What would be the height of the atmosphere if sea level pressure were 14.92 psia?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. 1)sketch (include everything in the system) 2)solution(step by step)
