Does a manometer (with one side open) measure absolute pressure or gauge pressure?

Does a manometer (with one side open) measure absolute pressure or gauge pressure? How about a barometer? A tire pressure gauge? A sphygmomanometer?

Expert Solution

The difference between the absolute pressure and the atmospheric pressure is called as gauge pressure.

Pguage = Pabs - Patm

Here, Pabs is the absolute pressure and Patm is the atmospheric pressure. Manometer, barometer, tire pressure gauge and sphygmomanometer are the devices to measure the pressure. Manometer with one side open is used to calculate the difference between atmospheric pressure and the gas pressure. it is used to calculate the gauge pressure. Barometer is used to calculate the absolute pressure. A tire pressure gauge and sphygmomanometer are used to calculate the gauge pressure.

A U- tube manometer is used to measure the pressure of oil of specific gravity 0.85 flowing in a pipe line. It is left end is connected to the pipe and right –limb id open to the atmosphere. The center of the pipe is 100 mm below the level of mercury (specific gravity =13.6) the right limb .if the difference of mercury level in the two limbs is 160 mm. determine the absolute pressure of the oil in the pipe.

Determine the resolution of a manometer required to measure the velocity of air at 50 m/s using a pitot tube and a mercury manometer to achieve an uncertainty in the velocity of 1.5 m/s. The air flows at 20 degrees C, 101.3 KPa demonstrate your result using the formulation of kline and McClintock.

When the flat open side of a charged coil was brought near the flat open side of the coil connected to a galvanometer (both coils parallel to each other), the galvanometer deflects very little. How do you know they need to be parallel and why is this the case? Where is north and south if the coil is acting like a bar magnet?

The accompanying sketch is that of a closed-end manometer. Describe how the gas pressure is measured. Why is a measurement of not necessary when using this manometer? Explain why the closed-end manometer is more suitable for measuring low pressures and the open-end manometer more suitable for measuring pressures nearer atmospheric pressure.

Find p1 the gauge pressure at the bottom of tube 1

A pair of vertical, open-ended glass tubes inserted into a horizontal pipe are often used together to measure flow velocity in the pipe, a configuration called a Venturi meter. Consider such an arrangement with a horizontal pipe carrying fluid of density \(p\). The fluid rises to heights \({h_{1}}\) and \({h_{2}}\) in the two open-ended tubes (see figure). The cross-sectional area of the pipe is A1 at the position of tube 1, and \({A_{2}}\) at the position of tube 2. Part...
