Pressure Measurement
Pressure measurement involves determining the force applied by a fluid (liquid or gas) over a certain area. It is typically expressed in units like pascals (Pa), atmospheres (atm), or pounds per square inch (psi). Devices used for measuring pressure include barometers for atmospheric pressure, manometers for liquids, and pressure gauges for various industrial applications. Understanding pressure is essential in fields like meteorology, engineering, and medicine, influencing everything from weather forecasting to the safe operation of machinery and the functioning of the human body.
