U Tube Manometer

The pressure difference head can then be expressed as. Gcse physics using liquid in a u tube to measure pressure difference duration.

The oldest type is the liquid column a vertical tube filled with mercury manometer invented by evangelista torricelli in 1643.

U tube manometer. A few conditions where this device may be specifically employed are discussed in this article. Hydrostatic gauges such as the mercury column manometer compare pressure to the hydrostatic force per unit area at the base of a column of fluid. U tube manometers the u tube manometer is the basic and most widely used style of manometer.

Dwyer flex tube series 1221 u tube manometer 200 0 200mm wc using red gauge fluid by dwyer a simple just quality unit by indyj this is a simple somewhat inexpensive yet adequate unit with a good range for many checks. P d 9 8 kn m 3 10 3 n kn 10 mm 10 3 m mm sin 45 o 69 3 n m 2 pa u tube manometer calculator. Example differential pressure measurement with an inclined u tube manometer.

Two types of pressure gauge left a u tube manometer in which differential pressure is measured as the difference h between the high pressure reading and the low pressure reading multiplied by the density of the liquid in the tube. U tube manometer principle and application duration. The u tube was invented by christiaan huygens in 1661.

We use the same data as in the example above except that the u tube is inclined 45 o. Right a bourdon tube gauge in which a coiled tube flattened into the cross section shown and attached to a fixed block is open to a pressurized fluid. A u tube manometer is used for measuring fluid and gas pressures under different conditions.

Glass manometer u tube built in stopcock mounted on back plate with printed scale 80 0 80 scale with 2mm subdivisions eisco labs 5 0 out of 5 stars 1 43 59 43. The method of using a u tube manometer for measuring liquid under moderate pressure liquid under vacuum gas under pressure or gas under vacuum are studied here and explained through neat illustrations. Manometers are available in varying designs depending upon application.

The manometer is commonly used to measure pressures ranging from as high as 100 inches of 2 95 red fluid 10 65 psi to the lowest vacuums of space and assist with calibrating pressure. Marine world 17 739 views.
