(1) 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.
(2) A patient recovering from surgery is being given fluid intravenously. The fluid has a density of 1040 kg/m3, and 9.54 10-4 m3 of it flows into the patient every five hours. Find the mass flow rate in kg/s.
