A tank of water open to the atmosphere is shown below. The depth of the water is h. There is a rectangular plate located on the left-hand side of the tank as shown. The location of the resultant force (center of pressure) on the plate, y, is given by: A. y = 0 B. y = h/3 C. y = h/2 D. y = 2h/3 E. y = h A U-tube manometer filled with water connects two tanks of air as shown below. The height of the water in the U-tube is as shown. The correct statement about the pressure of the two tanks is A) If PA is atmospheric pressure then pS is greater than atmospheric pressure B) The pressure in Tank B is higher than that in Tank A C) If pA is greater than atmospheric pressure then PBis also greater than atmospheric pressure D) If pA is less than atmospheric pressure then pB is greater than atmospheric pressure E )The pressure in Tank A is higher than that in Tank B Two tanks A and B that are filled with air at different pressures are shown below. Water filled manometers that are open to the atmosphere are connected to each, and the water levels are as shown. The figure that correctly shows the water levels when a single manometer joins the two taks is 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 yH of the horizontal force FH on the rectangular plate is given by: A. yH = h/3 B. yH = L/3 C. yH = h/2 D. yH = L/2 E. yH = (L - h)/3 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 relation for the pressure of Tank B relative to the pressure of Tank A is A) pB = pA + gamma (h3 - h2) B) pB = pA + gamma (h3 - h1) C) pB = pA - gamma (h3 - h2) D) pB = pA - gamma (h3 - h1) E) pB = pA - gamma (h2 - h1) A rectangular tank of water open to the atmosphere is shown below. The depth of the water is h. The figure that best describes the location of the resultant force (center of pressure) on the left hand side of the tank is A B C D
