Pressure measurement is the measurement of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum.
Learn how to measure pressure using gauge, absolute, and manometer methods. Gauge pressure is relative to atmospheric pressure, absolute pressure is the sum of gauge and atmospheric pressure, and manometer uses fluid levels to measure pressure differences.
Learn how to define and measure gauge pressure and absolute pressure, and how to use different types of pressure gauges, such as manometers and barometers. Explore the applications of pressure in daily life and science and engineering.
Learn about pressure, the ratio of force applied to the area covered, and its unit, the pascal. Explore the pressure ranges of various devices, events, phenomena, and processes, from the center of the Sun to a perfect vacuum.
There are a host of devices for measuring pressure, ranging from tire gauges to blood pressure cuffs. Pascal’s principle is of major importance in these devices. The undiminished transmission of pressure through a fluid allows precise remote sensing of pressures.
Manometers typically use a U-shaped tube of a fluid (often mercury) to measure pressure. A barometer (see Figure 14.13) is a device that typically uses a single column of mercury to measure atmospheric pressure.
