How is presure mesured?

Answer 1

Pressure is measured using various instruments, with the most common being manometers and pressure gauges. A manometer typically measures the height of a liquid column displaced by pressure, while pressure gauges often use a Bourdon tube or diaphragm to convert pressure into a readable format. Units of measurement for pressure include pascals (Pa), atmospheres (atm), and pounds per square inch (psi). The choice of measurement method and unit depends on the application and the range of pressures involved.
