A rectangular fuel storage tank 2.4m wide and 2m high has a volume of 40 m^3. It is placed horizontally so the top of the tank is 2 m below the ground surface. The empty weight of the tank is 24kN. A sudden rainstorm fills the area with water and everything becomes saturated. You should neglect any influence from the soil around the tank and especially above the tank. Assume it is just sitting with air around it. A). How high can the water rise above the bottom of the tank before it will begin to float? (the tank is empty) B.) The tank is full of diesel fuel (Sp Gravity .848) if the water level rises to the top of the tank would an anchor be needed to hold down the tank? C. If yes how much concrete would be needed (the density of concrete is 2320 kg/m^3 or specific weight 22.76kN/m^3).
