Function of manometer?
The function of a manometer is to measure the pressure of a fluid, usually a gas or a liquid. It consists of a sealed tube filled with the fluid being measured, with one end open to the environment and the other end connected to the source of pressure. As the pressure changes, the fluid in the manometer rises or falls, allowing the measurement of the 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.
What type of barometer was invented first the aneroid or the mercury?
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
Why must a barometer be open to the air at one end and close at the other end?
A barometer is used for measuring atmospheric pressure. The barometer sealed on the top with an open bottom in order to allow air pressure to push down.
When air pressuer increases what does the mercury in the barometer do?
Air is "pushed" into the open end of a barometer when the pressure is higher, meaning the mercury closer to the closed end of the barometer - where the pressure is measured - will rise.
What has a glass tube with the open end submerged in liquid mercury?
A manometer. Used to measure pressure.
Why must of barometer be open to the air at one end and close to the other?
becuase my peepaw said so
What is the function of U-tube manometer?
One of ends of the tube is used for pressure measurements, the other can be left open to the atmosphere to measure static pressure, or can be attached to the low end of a pressure system to measure differential pressure.
What part of the stethoscope do you use to listen to your heart open bell or closed bell?
You can use the bell and diaphragm. A closed bell opens the diaphragm, and a closed diaphragm opens the bell. It depends on what sounds you are looking for when deciding which side of the stethoscope to use.
How works manometer?
For a very basic explanation, a manometer measures the pressure differential between a closed pressure applied at one end and an open pressure at the other. For example. If you have a typical u-bend manometer and you apply an air pressure at one end, the liquid will raise correspondingly, as the pressure on the closed side increases more and more above the ambient air pressure. The amount it rises depends on the density of the liquid used and the diameter of the tubing. So basically a manometer uses the height of a liquid to translate the amount above ambient air pressure, which is considered zero, of your pressure source.
Is that the value for absolute pressure will always be greater than for gauge pressure?
No. We need to know exactly what is meant by gage here. A piston tyre gauge measures pressures relative to atmospheric. A mercury barometer measures absolute pressure. A gauge that involves uncoiling of a coiled tube will measure absolute pressure (it will have to be calibrated). But a manometer which is open to the atmosphere on one arm will measure pressures relative to atmospheric pressure so the real pressure is the two added together.
What is the pressure of the sample of gas trapped in the open-tube mercury manometer shown below if atmospheric pressure is 736 mmHg and h equals 9.2 cm?
(736-92)= 644 mmHG
