3 A 3 ft long gate of uniform density is closed at 45 with respect to the interface between water and oil Th width of the gate into the paper is 5 ft The specific gravity of oil is 0 8 where specific gravity is define by the ratio of density with respect to the density of water at the same temperature The gravitation acceleration is 32 2 ft s Note that Patm 1 94 slug ft Ignore friction at the hing 2116 lb ft and PH O a Using the manometer reading estimate the absolute pressure at the top of the tank inside b Evaluate the locations of centroid and center of pressure for the gate c Calculate the minimum weight of the gate so that it is kept closed hinge 3 ft 45 oil water 2 ft 3 ft
