Absolute pressure is the sum of gauge pressure and atmospheric pressure. Open-tube manometers have U-shaped tubes and one end is always open. They are used to measure pressure. A mercury barometer is a device that measures atmospheric pressure. The SI unit of pressure is the pascal (Pa), but several other units are commonly used.

Bernoulli’s principle is Bernoulli’s equation applied to situations in which the height of the fluid is constant. Bernoulli’s principle has many applications, including entrainment and velocity measurement.

Absolute pressure is the sum of gauge pressure and atmospheric pressure. Aneroid gauge measures pressure using a bellows-and-spring arrangement connected to the pointer of a calibrated scale. Open-tube manometers have U-shaped tubes and one end is always open. It is used to measure pressure. A mercury barometer is a device that measures atmospheric pressure.
