Given: 39ft. H2O
Conversions you can look up or know: 1ft=12in
1in=25.4mm
1mmHg=13.6mm H2O
39ft H2O (12in H2O/1ft H2O)(25.4mm H2O/1in H2O)(1mm Hg/13.6mm Hg)=
874.0588235 in calculator, but 874 with sig figs.

The atmospheric pressure in mm Hg can be calculated by converting the height of the water column into mm Hg. 39 feet is approximately 11887.2 mm Hg. This is based on the fact that the conversion of 1 ft is approximately 304.8 mm.

A glass column is filled with mercury and inverted in a pool of mercuryThe mercury column stabilizes at a height of 735 mm above the pool of mercuryWhat is the pressure of the atmosphere?
The height of the mercury column in the tube represents the balance between the atmospheric pressure pushing down and the pressure exerted by the column of mercury pushing up. With a height of 735 mm, the atmospheric pressure can be calculated as 735 mm Hg or 735 torr.
What happens when the mercury in barometer or manometer is replaced by water or any other less dense liquid than water?
If a less dense liquid than mercury, like water, is used in a barometer or manometer, the height of the liquid column would need to be much higher to achieve the same pressure comparison as mercury. This is because the density of the liquid affects the height needed to balance the atmospheric pressure. The instrument would still function, but the readings would be less sensitive due to the increased height of the liquid column.
A long glass tube sealed at one end that is filled with water has an inner diameter of 10 mm the tube and an atmospheric pressure is 755 mmHg how high is the column of water?
The atmospheric pressure of 755 mmHg can support a column of water up to 10.3 meters high. This is calculated using the equation h = (P / ρ*g), where P is the atmospheric pressure, ρ is the density of water, and g is the acceleration due to gravity.
If a barometer reads 535 mm Hg what is the atmospheric pressure expressed in centimeters of mercury?
mmHg represents the height of a column of mercury (Hg) in millimeters (mm) (as opposed to inches of mercury (inHg)). Since there are 10 mm (millimeters) in a centimeter, simply divide the mmHg by 10 and you find that 535mmHg is 53.5 centimeters Hg (cHg?).
What height would be maintained by a column of water inverted in a dish of water at sea level?
water is 1/13.5 as dense as mercury.Therefore, since mercury maintains a height of 760 mm at sea level:760/13.5 = 10,260 mm, or 10.26 meters
Why does the height of the column in a barometer changes as atmospheric pressure changes?
As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.
Why does the height of the liquid column in a barometer changes as atmospheric pressure changes?
Pressure tendancies measure short term weather. The mercury in a barometer will rise with atmospheric pressure denoting fairer weather and a fall in barometric pressure warns of inclement weather.
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather
Why must a barometer be place where are no temperature extremes?
The height of the mercury column is used to measure atmospheric pressure. If the barometer is also subjected to high temperatures, the thermal expansion of the mercury column will indicate a higher pressure than is really the case. This will make the barometer readings useless.
As air pressure increases does the height of a column of mercury in a barometer increase?
Yes, as air pressure increases, the height of the column of mercury in a barometer also increases. This is because the higher air pressure pushes down on the mercury in the barometer, causing the column to rise. Conversely, lower air pressure will cause the column of mercury to fall.
What does a decrease in the height of a column in a mercury barometer mean?
air pressure is decreasing
Why water is not used as the medium for measurement of atmospheric pressure?
Water is not used as the medium for measurement of atmospheric pressure because it is not practical for high-precision measurements due to its relatively low density and high vapor pressure at room temperature. Mercury is commonly used because it has a high density, low vapor pressure, and does not wet glass, allowing for accurate and consistent measurements to be taken.
A decrease in the height of a column in a mercury barometer means that .'s surface?
When air pressure increases, the mercury in a barometer rises.
Antique aneroid barometer has a scale of 28 to 31 what units are these?
The scale on an aneroid barometer between 28 and 31 typically represents atmospheric pressure in inches of mercury (inHg) or millibars (mb). These units measure the pressure exerted by the Earth's atmosphere at a specific location.
What would happen to a mercury barometer when the air pressure is getting lower?
The height of the column of mercury would be lower.
When air pressure increases the liquid in a mercury barometer would what?
The height of the Mercury column would decrease.
