Question

Explain the working of a manometer.​

Answer 1

Answer:

The manometer consists of a U shaped tube in which the liquid is filled. - This is used to measure the pressure which is unknown by the balancing gravity force and acceleration due to gravity. - The scales are made on the tube in terms of mm.

Answer 2

A manometer is a device that measures air pressure using a container with a "U"-shaped tube open at one or both ends. The height of the fluid on the open side will be higher on that side when air pressure is less than the gas pressure and lower on the open side when the air pressure exceeds the gas pressure.

A manometer works on the principle of hydrostatic equilibrium and is used for measuring the pressure (static pressure) exerted by a still liquid or gas. Hydrostatic equilibrium states that the pressure at any point in a fluid at rest is equal, and its value is just the weight of the overlying fluid.
