Pressure is the amount of acing on a unit . It can be calculate using the P = F/A. It is measured in N/m2 or (Pa). A barometer is used to measure pressure. When the atmospheric pressure is low, windy, cloudy and weather usually results. High atmospheric pressure usually leads to , settled weather. The lines in a weather chart that link places of eaqual pressure are called . The pressure in a fluid with depth, and decreases with height above sea level. A can thus be used to measure height. This instrument is known as an . In a fluid, the pressure at a point acts in all directions. Pressure can be through fluids. This is made use of in braking systems, industrial and power .
