A U tube with both end open to the atmosphere A wind with speed 40 m/s blows parallel to the roof of a house. The area of the roof is 250 m^2. Assuming that the pressure inside the house is atmospheric pressure is partially filled with water Oil the force exerted by the wind on the roof and the direction of the force will be (ρair​=1.2 kg/m^3) which is immiscible with water
