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.
Water Pressure Tanks: What Are They and How Do They Work? When you open a spigot in your home, you expect water to flow at a certain speed. Water pressure in the line causes that water to flow. If your home is on city utilities, water pressure is controlled (for the most part) by the city. If your home is on a well, you need something to build that pressure and this is the purpose of the pressure tank. In a nutshell: The pressure tank in a water well system creates water pressure by using compressed air to bear down on the water. Because of this pressure, when a valve is opened water is pushed out of the tank through the pipes in your home.
