What is the height of the water in a vacuum column when the atmospheric pressure is...
You wish to observe the progress of your vacuum pump in evacuating a tall bell jar for the purpose of demonstrating that sound waves do not travel in a vacuum. So you place a mercury barometer inside the bell jar and follow the height of the mercury column as the pump chugs away. When you observe a height of 5.67 mm, what fraction of atmospheric pressure, expressed as a percentage, have you achieved in your bell jar? The density of...
If you dive to 15 m below the surface of a lake, what is the pressure due to the water alone? Assume that the density of water is 1000 kg/m3; g = 9.8 m/s2; and PATM = 1.01 x 105 Pa.
Jorge wishes to observe the progress of his vacuum pump in evacuating a tall bell jar for the purpose of demonstrating that sound waves do not travel in a vacuum. So, Jorge places a mercury barometer inside the bell jar and follows the height of the mercury column as the pump chugs away. When he observes a height of 5.59 mm, what fraction of atmospheric pressure, expressed as a percentage, has Jorge achieved in his bell jar? The density of...
What is height in m of a column of water when the applied pressure on the other arm of a J tube sealed at one end is 1717.2 hPa? The density of water at 20.00 0C is 0.998 g cm-3. The acceleration of gravity is 9.80665 m/s-2
What is height in m of a column of water when the applied pressure on the other arm of a J tube sealed at one end is 2665.1 hPa? The density of water at 20.00 0C is 0.998 g cm-3. The acceleration of gravity is 9.80665 m s-2.
4) Calculate the height of a column of ethanol that would be supported by atmospheric pressure (2atm). The density of ethanol is 0.789 g/cm'. A) 1.28 x 10m B) 0.039 m C) 25.68 m D) 13.0 m E) 3900 mm
1. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 699 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 699 2. An automobile tire is inflated to a pressure of 29.2 psi. Express this pressure in atmospheres, kilopascals, inches Hg,...
An atmospheric diving suit can be used for very deep dives of up 700 m under the sea level. Calculate the pressure experienced by the suit at this depth (note: the atmospheric pressure on Earth at the sea level P0= 1.01 x105 Pa ; density of water = 1000 kg/m3) Select one: a. 5.49 x 105 Pa b. 6.96 x 106 Pa c. 8.11 x 107 Pa d. 1.33 x 108 Pa e. None of the above
Create the worksheet shown in Figure 1.35 and use it to
determine the pressure at the bottom of the columns of fluid
specified below. [Do not consider any imposed pressure (e.g., air
pressure) on the top of the column.]
a.A column of water 10 m high (SGwater
=1.0)
b. A column of seawater 11,000 m high. This is the
depth of the Marianas Trench, the deepest spot known in the earth’s
oceans (SGseawater = 1.03) (ignore the variation in water...
(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?
