.'. 2 n3 x 62*5 = pressure on the four sides. Then n3 x 62 • 5 : 2 n3 x 62 • 5 : : 1 : 2 ; that is, the pressure on the sides is = to twice the pressure on the ba se. In these calculations the fluid is supposed to be at rest, and acted on only by gravity. Let A B C D be a vessel filled with water,… … Area of the triangle AD F = 12 x \- = 72 sq. ft., , 72 x 21 = 1512 cub. ft. content of the wedge. /. 1512 x 62-5 = 94500 lbs. pressure. Before it was stated that the pressure in lbs. on the side is equal to a column of water whose base is the area of the surface, and perpendicular height the depth…
