Why Mercury is used in manometer?
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 .
To measure a pressure above atmospheric pressure you would use?
A pressure gauge or manometer is typically used to measure pressure above atmospheric pressure. These devices can accurately measure the pressure difference between the system being measured and atmospheric pressure.
Is thermometer a type of manometer?
Not quite; This is what the first source said about how a thermometer works; This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. In other words, the thermometer goes up or down due to the expansion of the alcohol or mercury due to the heat. After reviewing the second source, you will see that the columns go up and down due to the atmospheric pressure. If it goes up and down due to atmospheric pressure it is a manometer. A manometer does not work if it is not exposed to the atmosphere. A thermometer is sealed off to the outside. This is another reason why a thermometer is different from a manometer.
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.
Inverted U-tube differential manometers?
Inverted U-tube manometer is used for measuring pressure differences in liquids. The space above the liquid in the manometer is filled with air which can be admitted or expelled through the tap on the top, in order to adjust the level of the liquid in the manometer.
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.
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 an inverted YouTube manometer more sensitive than upright manometer?
Inverted U-tube manometer is used for measuring pressure differences in liquids. The space above the liquid in the manometer is filled with air which can be admitted or expelled through the tap on the top, in order to adjust the level of the liquid in the manometer. Equating the pressure at the level XX'(pressure at the same level in a continuous body of static fluid is equal), For the left hand side: Px = P1 - rg(h+a) For the right hand side: Px' = P2 - (rga + rmgh) Since Px = Px' P1 - rg(h+a) = P2 - (rga + rmgh) P1 - P2 = (r - rm)gh If the manometric fluid is choosen in such a way that rm << r then, P1 - P2 = rgh. For inverted U - tube manometer the manometric fluid is usually air.
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.
What is the instrument used to determine air pressure is called?
The instrument used to determine air pressure is called a barometer. A simple barometer is a long glass tube filled with mercury that it turned upside down into another container filled with mercury.
