Question

Problem 3 (4 pts.). A bathyscaphe (a small free-diving self-propelled deep-sea submersible), is a sphere of radius RE 1.5 m located 873.5 m below the sea level. a) What is the pressure exerted on its surface (here you can neglect the size of the bathyscaphe compared to the depth of its immersion) and the buoyant force acting on it in the water to) Il a small leak is opened at the top of the bathyscaphe, with what speed will the water enter IL The pressure inside the bathyscaphe is n. 13 where = 1.01 -10° Pa is the atmospace pressure. (C) We need to make sure that our bathyscaphe will not be completely filled with the water for at least 20 minutes. What air pressure should be created inside the bathyscaphe if the area of the opening 18 1.07 cm? You may assume that the pressure inside the bathyscaphe does not change while it is being filled with water. 2R H = 873.5m R=1.5m Figure 3: Schematic graph for Problem 3.
