A two-dimensional gate is submerged in water. The figure that best represents the pressure distribution of the water on the left hand (water) side of the gate is A U-tube manometer filled with water connects two tanks of air at different pressures as shown below. The height of the water in the U-tube is as shown. The water specific weight is y. The pressure different (p A - p B) is A. (p A - p B) = y (h3 - h2) B. (p A - p B) = -y (h3 - h2) C. (P A - P B) = y (h3 - h1) D. (p A- p B) = -y (h3 - h1) E. (p A - P B) = y (h2 - h1) A tank of water of depth h that is open to the atmosphere is shown below. There is a rectangular plate located on the left-hand side of the bottom of the tank as shown. The location of the resultant force (center or pressure) on the plate, xc, is given by: A. x c = h/2 B. x c = L/3 c. x c = h/2 D. x c = L/2 E. x c = L A tank of water open to the atmosphere with a depth h is shown below. The left side of the tank is at an angle. The location yv of the resultant vertical force on the rectangular plate is given by: A. y = h/3 B. y = L/3 C. y = h/2 D. y = L/2 E. y = (L - h)/3 Two takes filled with air and connected by water-filled manometers are shown. The water levels are as shown. The gage pressure (the pressure relative to atmospheric) for Tank A is A) pA equals + p" B) PA equals + 1" C) PA equals 0" D) PA equals - 1" E) pA equals - 3"
