Question

write a note on the structure and function of manometer?​

Answer 1

A simple manometer consists of a glass tube having one of its ends connected to a point where pressure is to be measured and other end remains open to atmosphere. A differential manometer is a device that measures the difference in pressure between two places.

Common types of simple manometers are –

Piezometer

U-tube manometer

Common types of differential manometers are –

U-tube differential manometer

Inverted U-tube differential manometer

Answer 2

A manometer is a gadget that works on the hydrostatic equilibrium concept. The pressure at any location in a fluid at rest is equal, and its value is equal to the weight of the overlying liquid, according to hydrostatic equilibrium.

Explanation:

• A manometer is a U-shaped tube with one arm closed and connected to the gas to be measured, with a non-volatile liquid (typically mercury) in between. The principle of hydrostatic equilibrium governs the operation of a manometer.
• This gadget is primarily used to properly monitor modest pressure variations. Let's apply the principle of hydrostatic equilibrium to the diagram above. The pressure at the top of the liquid is equivalent to air pressure because the left tube is open.
• Other process variables that are a function of pressure can be easily measured using a manometer in addition to direct pressure and vacuum measurement. Flow, filter pressure drop, metre calibrations, leak testing, and tank liquid level are all common applications.
