As the depth in a fluid increases, the pressure increases due to the larger weight of the column of fluid above.
At what depth, in meters, a column of mercury is the pressure 1.00 atm? The density of mercury is 13.6 × 103 kg/m3?
At what depth, in meters, a column of mercury is the pressure 1.00 atm? The density of mercury is 13.6 × 103 kg/m3?
a) Find the density of air (in kg/m3) at a pressure of 1.00 atm and a temperature of 35.0°C, assuming that air is 78% N2, 21% O2, and 1% Ar. kg/m3 b) Find the density of the atmosphere on Venus (in kg/m3), assuming that it's 96% CO2 and 4% N2, with a temperature of 724 K and a pressure of 92.0 atm.
(a) How high in meters must a column of water be to exert a pressure equal to that of a 760-mm column of mercury? The density of water is 1.0 g/mL whereas that of mercury is 13.6 g/mL (b) What is the pressure, in atmospheres, on the body of a diver if he or she is 39 ft below the surface of the water when atmospheric pressure at the surface is 0.97 atm?
The sperm whale can dive to a depth of 2250 meters. For sea water with a density of 1020 kg/m3 what is the difference in pressure at this depth as compared to the surface? Supply your answer in atmospheres" (atm), where 1 atm approximately equals 1x105 Pa. (This is an incredibly large pressure. Human bodies would be crushed. The deepest human dive recorded was around 300 m, and even then, the diver had to spend 12 hours to surface from...
What pressure (in atm) is exerted by a column of mercury 1.40 m high? The density of mercury is 13.5951 g/cm^3.
Pressure and Archimedes' Principle 2. Liquid mercury, which has a density of 13600 kg/m3, is commonly used in barometers to measure air pressure. A U-shaped tube closed at one end contains some mercury at the closed end (see figure) and vacuum above the mercury. Air in the open end exerts pressure on the mercury, and the mercury level rises until the mercury pressure in the closed end equals the air pressure in the open end. The height difference h between...
The density of mercury is 13.6 g/cm 3. What is the density of mercury in kg/m 3? Show work please
What is the gauge pressure (in Pascals) at a depth of 3.13m below the surface of a swimming pool Assume the density of water is 1000 kg/m QUESTION 2 At what depth (in meters) in the ocean is the gauge pressure 10 times larger than atmospheric pressure? Assume that the density of water in the ocean is 1000 kg/m3 and that atmospheric pressure is 101,325 Pa
The human brain and spinal cord are immersed in the cerebrospinal fluid. The fluid is normally continuous between the cranial and spinal cavities and exerts a pressure of 100 to 200 mm of H2O above the prevailing atmospheric pressure. In medical work, pressures are often measured in units of mm of H2O because body fluids, including the cerebrospinal fluid, typically have nearly the same density as water. The pressure of the cerebrospinal fluid can be measured by means of a...
A block of steel (density of 8.05 x 103 kg/m3) with a mass of 1.50 kg is suspended (in equilibrium) by an ideal spring scale. The block is completely immersed in water (density of 1.00 x 103 kg/m3). What is the reading in the spring scale?
13. To measure moderately low pressures oil with a density of8.0 x 102 kg/m' is used in place of mercury in a barometer. A change in the oil column of 1.0 mm indicates a change in pressure of about: A) 1.2 x 104 Pa B) 0.078 Pa C) 0.85 Pa D) 7.8 Pa E) 8.3 Pa 14. The principle of fluid pressure which is used in hydraulic brakes or lifts is that: A) pressure is the same at all levels...
