The submarine can dive a distance of 50 ft from the floating position in about 30 s. Diving is accomplished by taking water into the ballast tank so the submarine will sink.

Consider a rectangular plate of width B = 1m (measured in the direction normal to the plane of this sheet) and negligible thickness, which separates two fluids of densities ρ and ρw. A mass of density ρs is supported by an inextensible rope that passes through a pulley connected to one end of the plate. Consider that ρ = 1.59ρw and ρs = 2.40ρw, where ρw = 1000 kg/m3. Determine the volume that this mass must have for the system to remain in equilibrium, as shown in the figure.
Oil is filled within a tall cylindrical tank. A flat disk with a height of 1 cm and with a diameter of 5 cm is placed into the oil. There occurs a narrow spacing of 0.1 mm between the disk and the tank wall. Due to the forces acting on the disk, it moves downward, and after some time, the speed of the disk reaches a terminal velocity. Beyond this moment, measurements reveal that the disk moves 30 cm in 4 seconds. If the oil density is 600 kg/m3and the specific gravity of the disk is 1.5, determine the oil’s viscosity.
