For Questions 5 - 9 A smooth sphere of diameter d is dropped into a calm ocean. Data: d = 20 cm; Sphere material's density psp = 3000 kg/m3; Sea-water density psw = 1025 kg/m3, viscosity Psw = 1.002×103 Pa.s, temperature 20°C. B is buoyancy force on the sphere (numerical value only; no sign); similarly FD is the drag force on it, and W its weight; Cp is the drag coefficient. The sphere's steady sinking velocity is V (in m/s), assuming that the ocean is of sufficient depth such that V has been attained. Volume of a sphere of diameter d is Tid/6. Make other reasonable assumptions.
