Measuring Liquid Pressure

Measuring Liquid Pressure

An instrument used to measure the pressure of a liquid is known as a pressure gauge. The simplest form of the pressure gauge is a manometer, which measures the pressure difference.

Pressure

Pressure is the force exerted per unit area. For a constant force, the smaller the area the greater the pressure, and the bigger the area the smaller the pressure. The SI unit of pressure is newton per square metre or pascal.

Pressure in Liquids

The pressure exerted by a liquid at a point inside it is directly proportional to its depth, density, and acceleration due to gravity. The pressure exerted by a liquid at points which are at the same level in the liquid is equal. The pressure due...Show More
