The gauge pressure of the air in the tank shown in the figure is measured to be 56 kPa.  Determine the differential height h of the mercury column.

Determine the height h of the column of mercury in the tube if the level of water in the tube is 0.2 m and the dimensions of the oil and the water listed in the diagram. Let poil = 900 kg/m³, pwater = 1000 kg/m³, PMercury = 13,500 kg/m³. A 0.4 m Oil B 0.3 m h Water Mercury 0.2 m

A closed cylindrical tank filled with water has a hemispherical dome and is connected to an inverted piping system as shown in the figure below. The liquid in the top part of the piping system has a specific gravity of 0.8, and the remaining parts of the system are filled with water. If the pressure gage reading at point A is 60 kPa, determine (a) the pressure in the pipe at B, and (b) the pressure head, in millimeters of mercury, at point C. 3m 7m C L 3m 2m -B

The tank contains water and is pressurized by air, and the pressure is measured by a multi-fluid manometer as shown in the figure. The tank is located on a mountain at an altitude of 1400 m where the atmospheric pressure is 85.6 kPa. Determine the air pressure in the tank if h1 = 0.1m, h2 = 0.2m, and h3 = 0.35m. Take the densities of water, oil, and mercury to be 1000 kg/m3, 850 kg/m3, and 13,600 kg/m3, respectively. AIR ! WATER 4:4 Mercury Oil N

The flow of water from a container is controlled by a 5-ft-wide L-shaped gate hinged at point A, as shown in the figure. If it is desired that the gate open when the height of the water is 10 ft, determine the weight W of the counterweight to achieve this. Take d= 5 ft and H = 16 ft. Give your answer in lb and without decimals.
