(a) To place a subsea device on the seabed, an operational ship releases a balloon (a smooth sphere) with the device attached. The total weight of the balloon and device in sea water is 7.3 kg. Calculate the required balloon diameter d so that the device touches the seabed at a velocity no greater than 2 m/s. Assume the drag force due to the device itself is negligible compared to the drag force due to the balloon. For your considerations: sea water density is 1025 kg/m³ and sea water kinematic viscosity is 1.05x10 m2/s.
