Step 1

A manometer is a U-shaped tube filled with a liquid, usually mercury. One end of the tube is connected to the container with the gas whose pressure we want to measure, and the other end is open to the atmosphere. Show more…

Key Concepts

Manometer

A manometer is an instrument used to measure the pressure of a fluid by balancing the fluid column against the pressure of the gas or liquid being measured. It typically consists of a U-shaped tube partially filled with a liquid where the difference in levels corresponds to the pressure difference, making it a practical tool for both qualitative and quantitative pressure assessments.

Hydrostatic Pressure

Hydrostatic pressure is the pressure exerted by a fluid at equilibrium due to the force of gravity. It is central to the operation of a manometer, as the height difference in a fluid column is directly proportional to the pressure difference, based on the fluid density and gravitational acceleration.

Pressure Measurement

Pressure measurement is the process of determining the force applied per unit area in a system. Instruments like manometers apply the principles of fluid statics to convert differences in fluid column heights into pressure readings, which is essential in many industrial, scientific, and engineering applications.
