Instead an organization named the Association for Intercollegiate Athletics for Women (AIAW) governed women's collegiate sports in the United States. By 1982, however, all divisions of the NCAA offered national championship events for women's athletics and most members of the AIAW joined the NCAA.
Mechanical pressure gauges are connected directly to the process fluid being measured (i.e. oil). As the process fluid pressure changes the pressure on the bourdon tube also changes which in turn moves the pointer on the gauge. Mechanical temperature gauges also utilize a bourdon tube. They have a sealed capillary tube and bulb assembly that is filled with temperature sensitive liquid that produces a proportional vapor pressure on the bourdon tube.
Manometers are used to measure pressure exerted by fluids. It works on the principle of Pascal's law. Pascal's law states; In a closed system containing fluid at rest,change in pressure is transferred undiminished through out the fluid. Manometer uses a column of liquid to measure pressure (generally relative to the atmospheric pressure).The instrument is attached to the system whose pressure is to measured. If the pressure is greater than atmospheric pressure,the height of the liquid column increases.
