Mercury is used due to its higher specific gravity allowing the manometer physical size to be smaller in direct proportion to the weight of mercury vs weight of water.and its vapour pressure is negligible.these are the two reasons .

What happen when mercury used in inverted manometer?

When mercury is used a manometer fluid and the manometer tube is inverted it will measure the small pressure difference in liquids. This is a tool used by scientists.


Is manometer used to measure the pressure of liquid?

yes,manometer is an instrument . It is used to measure pressure of liquid.

What has a glass tube with the open end submerged in liquid mercury?

A manometer. Used to measure pressure.


How does a mercury pressure device work?

A mercury pressure device, such as a manometer, works based on the principle that the pressure of a fluid is directly proportional to the height of the fluid column. In a mercury manometer, a column of mercury is used to measure the pressure difference between two points. The difference in height of the mercury column indicates the pressure difference between the two points.


Who invented the mercury manometer?

The mercury manometer was invented by Evangelista Torricelli in 1643. Torricelli was an Italian physicist and mathematician who discovered that the height of a column of mercury in a tube varied with atmospheric pressure, leading to the creation of the mercury manometer for measuring pressure.


What kind of water used in manometer?

A manometer typically uses a liquid such as mercury or a colored oil to measure pressure. The specific type of liquid used depends on the requirements of the measurement and the accuracy needed. Water is not usually used in manometers as it has lower density and may not provide accurate readings.


How do you use a manometer?

A manometer is a device that is used to measure the pressure of a fluid. The U-shaped glass tube is partially filled with a liquid, usually mercury. The difference between the height of the mercury corresponds to the difference between the pressure of the fluid in the container and the atmospheric pressure.


What is an open arm manometer?

It is a type of manometer, an object used to measure the pressure of different things, and the open armed manometer allows for the atmospheric pressure in the tube of the manometer. So the sample gas pressure pushes on the mercury that is already being pushed on by the atmospheric pressure. Then you add the atmospheric pressure to the change in the mercury (in mm) and that gives you your pressure. It's like a tire gauge.


Why is mercury a better liquid to use in manometer than water?

Water can be used up to only 100 degree celsius. mercury can be used 356 degree celsius Water has a tendency to evaporate. The density of water is about 13 times lower than that of mercury, so some pressure levels would need a very large manometer tube.


Why mercury is not used in inverted U-tube manometer?

Mercury is a dense and toxic liquid metal that can be hazardous to handle. Using mercury in an inverted U-tube manometer may pose a safety risk due to the potential for spills or leaks. Additionally, mercury is a costly material compared to other less toxic and easy-to-use liquids such as water or oil.


How do you set up manometer?

To set up a manometer, first ensure that it is securely mounted in a vertical position. Fill the manometer with a fluid, typically mercury or water, making sure there are no air bubbles. Connect the manometer to the system you want to measure the pressure of, and then observe the height difference of the fluid levels in the manometer to determine the pressure.
