In preparation for a demonstration, your professor brings a1.5-L bottle of sulfur dioxide into the lecture hall before class toallow the gas to reach room temperature. If the pressure gaugereads 85 psi and the temperature in the hall is 23°C, how manymoles of sulfur dioxide are in the bottle?
34.) 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 88 kPa. Determine the air pressure (kPa) in the tank if h 1 = 0.2 m, h 2 = 0.3 m, and h 3 = 0.45 m. Take the densities of water, oil, and mercury to be 1000 ??/?3, 840 ??/?3, and 13,600 ??/?3, respectively. (Answer with 3 decimal places, do not include the units)
A closed container contains 1.5m high of water, 2.5m high of oil (SG= 0.8), an unknown liquid (SG= 1.25) whose height is 1.6m, and the pressure at the top of the mixture is 17 KPa. Determine the pressure head at the bottom of the container in millimeters of mercury (SG= 13.6)
Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb = ? airgVballoon, will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 70 kg each, Determine the maximum amount of load, in kg . Assume the density of air is ? =1.16kg/m3, and neglect the weight of the ropes and the cage
An iron block of unknown mass at 185°F is dropped into an insulated tank that contains 0.8 ft3 of water at 70°F. At the same time, a paddle wheel driven by a 200-W motor is activated to stir the water. Thermal equilibrium is established after 10 min with a final temperature of 75°F. Determine the mass of the iron block.
A. Nitrogen at a temperature of 310°F occupies a volume of 10.58 cu. ft. If the initial volume is maintained constant and the pressure tripled, determine the final temperature in K. B. If 100 ft3 of atmospheric air at zero Fahrenheit temperature are compressed to a volume of 1 ft3 at temperature of 200°F, what will be the gauge pressure of the air in psi?
Measuring the drop in pressure with a manometer as a function of temperature within a sealed container filled with an ideal gas provides a technique to show that the magnitude of "zero absolute temperature" or OK corresponds to -273 °C. If this experiment is conducted, starting at 1 atm and 67 °C, instead of in boiling water, what will the pressure be, in mmHg, when cooled to 0°C?
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
