Pressure Crossword Clue

Meaning

Pressure is a force applied perpendicular to the surface of an object. It can be caused by a variety of factors, such as the weight of an object, the force of a fluid, or the tension in a string.

Units of Measurement

The SI unit of pressure is the pascal (Pa), which is defined as one newton per square meter (N/m^2). Other common units of pressure include the bar, the atmosphere (atm), and the pound per square inch (psi).

Types of Pressure

There are several different types of pressure, including:

• Gauge pressure is the pressure relative to the surrounding atmospheric pressure.
• Absolute pressure is the pressure relative to a perfect vacuum.
• Hydrostatic pressure is the pressure exerted by a fluid at rest due to its weight.
• Aerostatic pressure is the pressure exerted by a gas at rest due to its weight.

Applications of Pressure

Pressure is a fundamental concept in many areas of science and engineering, including:

• Fluid mechanics: Pressure is used to describe the flow of fluids.
• Solid mechanics: Pressure is used to describe the forces acting on solids.
• Thermodynamics: Pressure is used to describe the state of a gas.
• Meteorology: Pressure is used to describe the weather.
