The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer. 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 = 0.1 m, h2 = 0.2 m, and h3 = 0.35 m. Take the densities of water, oil, and mercury to be 1000 kg/m3 , 850 kg/m3 , and 13,600 kg/m3 , respectively
The helium-filled blimp shown in the figure below is used at various athletic events. Determine the number of pounds of helium (lbm) within it if its volume is 68,000 ft3 and the temperature and pressure are 80 °F and 14.2 psia, respectively. The gas constant for helium is 1.242×104 (ft-lbf)/(slug-R).
A tank is divided into two sections by a 1x1-m square gate that is hinged at A . A couple with a magnitude of 490 N·m is required for the gate to rotate. If one side of the tank is filled with water at the rate of 0.1 m3 /min and the other side is filled simultaneously with methyl alcohol (density Pma = 789 kg/m3 ) at the rate of 0.2 m3 /min, determine at what time and in which direction the gate will rotate.
