If pressure is stated in inches that means inches of what?
Inches of mercury. It is so named because it originates from a certain pressure measurement tool that includes a column of liquid mercury.
What pressure in m is equal to 30 inches of mercury?
30 inches = 0.762 metres
What is the diameter of mercury in inches?
Mercury is 3 inches
How do you convert inches Mercury to ATM?
Multiply inches of mercury by 0.033421057 to get atmospheres.
1 atmosphere is How many inches of mercury?
29.925 inches of mercury is 1 atmosphere.
What deos a barometer measure?
A barometer is used to measure air pressure. It measures the atmospheric pressure using air, mercury, or water and will be shown as inches of mercury or millibars.
What does the pressure units in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of Mercury on a mercury barometer
What does the pressure units 30.03 in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of mercury on a mercury barometer
How can an aneroid barometer give reading in inches of mercury when it doesn't use any mercury?
Good question.Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring.Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did not actually use any mercury.
A pressure gauge reads57 psi The equivalent pressure in inches of mercury absolute is?
To convert psi to inches of mercury absolute, divide the psi value by 2.036. In this case, 57 psi divided by 2.036 is approximately 27.97 inches of mercury absolute.
What are the units of measurements of an aneroid barometer?
The units of measurement for an aneroid barometer are typically in inches of mercury (inHg) or millibars (mb). These units represent the atmospheric pressure being measured by the instrument.
What is the absolute pressure at 20 inches of mercury?
The absolute pressure at 20 inches of mercury is approximately 10.3 psi (pounds per square inch). This is calculated by adding the atmospheric pressure (14.7 psi) to the gauge pressure or vacuum pressure (negative in this case) represented by the 20 inches of mercury column.
A barometer registers a reading of 12.6 psi what is the equivalent pressure in inches of mercury?
To convert psi to inches of mercury, multiply the psi value by 2.036. Therefore, 12.6 psi is equivalent to approximately 25.65 inches of mercury.
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.
When the height of the mercury in a barometer is 29.92 inches the barometric pressure is?
When the height of the mercury in a barometer is 29.92 inches, the barometric pressure is equivalent to standard atmospheric pressure at sea level, which is 1013.25 millibars or 14.7 pounds per square inch (psi).
What unit of measurement does an barometer use?
Barometric pressure is usually measured in inches of mercury, millibars (mb), or hectoPascals (hP).
What units are used on an antique Danish barometer with a scale of 24.6 t0 29.6?
Just as a guess, they're probably inches of mercury. Standard air pressure is set at 29.92 inches of mercury.
