There is tank having pressured air and layered fluid in it. First layer fluid density is 2=1000 kg/m3 and second layer density 2=1040 kg/m3. A block with a density of 2400 kg/m3 is attached to the center of gravity of circular plate by a cable.The volume of block is V=0.05 m3. The block is totaly immersed in the fluid. Half of the block volume is in the first layer and the other half is in the second layer of the fluid. The plate closes a circular hole of diameter D=0.5 m. The weight of the plate is 100 N. An inclined tube manometer is attached to the tank with mecury as the fluid. The specific gravity of mercury is SG=13.6. Neglect the weight of the air on the manometer reading.The width of the tank is B=2 m. a) Draw the pressure distribution acting on the block per unit width. b) Determine the manometer reading h just before the plate starts to lift off the hole.
