Determine the minimum diameter to maintain stable conditions for a warming bouy. The centre of gravity is 750 mm above the base. It has a height of 2,75 m and a relative density of 0,55. It should float with its longitudinal axis in the vertical plane in seawater with a density of 1025kg/m^3.
density of buoy = 0.55 × 1025kg/m³ = 563.75kg/m³
