A boat having a mass of 80 Mg rests on the bottom of the lake and displaces 11.75 m^3 of water. Since the lifting capacity of the crane is only F = 550 kN, two balloons are attached to the sides of the boat and filled with air. The volume of a sphere is V =4/3πr^3. ρw = 1000 kg/m^3.Determine the smallest radius r of each spherical balloon that is needed to lift the boat. Neglect the mass of air and of the balloon for the calculation required for the lift and What is the mass of air in each balloon if the air and water temperature is 12∘C? The balloons are at an average depth of 20 mm. The gas constant for air is R= 286.9 J/(kg⋅K)
