The tube has to be at least as long as the amount dipping in the mercury + head space + the maximum length of the column. The pressure is shown on your barometer’s dial, usually expressed in “inches” referring to “inches of mercury” (inch Hg). The early barometers measured the ...
The two types of barometers are mercury and aneroid. In a mercury barometer, millibars measure how high the mercury column climbs a vertical glass tube. Aneroid barometers don't use liquid of any kind, instead employing a flexible-walled evacuated capsule. Types Types Aside from millibars, ...
inches Hg or inches of mercury (inHg). Elsewhere, units of millibars (mb) or hectopascals (hPa) are used; however, it can also be described using torr (mm Hg), or pounds per square inch (psi). The instrument used to measure barometric pressure is called a barometer. Barometers are a...
The barometer in my lab says the pressure is 0.905 atm. What is this pressure expressed in torr? The density of mercury is 13.5 g/mL and the density of water is 1.00 g/mL. If a mercury barometer reads 805 mmHg, what is the barometric pressure in cmH2O?...
