PPT-Air Pressure

Air molecules are moving constantly They bounce off everything like rubber balls They are bouncing off your body and everything around you right now Each time an air molecule bounces off an object it pushes EXERTS FORCE on that object When billions of air molecules bounce off a surface the force is spread over the area of that surface. Set-Up and Safety. High-Pressure Air Bags. This PowerPoint is intended as a general review of high-pressure air bag set-up and safety practices.. There are various different air bag systems currently used in Snohomish County. Always refer to your departments SOP/SOG’s as well as manufacturers recommendations prior to use.. • Pressure gradient controlled by ‘hydrostatic equilibrium’ — pressure supports weight of gas above it, and, because it is gas, density drops with decreasing pressure; combination of effects leads to e-folding drop in pressure over . PRESSURE. “press” = push on a surface. Pressure = Force/ surface area. P= F/ SA. Unit: . pascal (Pa) =1 N/m. 2. Who exerts more pressure on the ground an . elephant. or a . woman . Key Concepts: What are some of the properties of air?. What instruments are used to measure air pressure?. How does increasing altitude affect air pressure and density?. Key terms:. Density, pressure, air pressure, barometer, mercury barometer, aneroid barometer, altitude. 1. Physics 1. Air Pressure 2. Air Pressure and Altitude 3. Weather Fronts 4. Barometric Pressure 2. Kestrel Altimeters 1. BARO Function 2. ALTITUDE Function 3. Examples 1. Monitoring Barometric Pressu Low Pressure. H is for . “HIGH PRESSURE”. H is for . HEAVY. BLUE = . COOL. Cool air . contracts. Cool air sinks . because COOL air is HEAVIER. Sunny but slightly cooler weather. Heavy shoves clouds out of the way. 2. The denser the atmosphere…. the greater its weight, and . the greater its air pressure.. 3. atmospheric pressure -. . a.k.a. .; . barometric pressure or air pressure.. the pressure due to the weight of the overlying atmosphere.. Understand the relationship between pressure, force, and area.. Solve problems about pressure.. Investigate the relationship between pressure and depth in a liquid.. Show that air has mass and occupies space.. Set-Up and Safety. High-Pressure Air Bags. This PowerPoint is intended as a general review of high-pressure air bag set-up and safety practices.. There are various different air bag systems currently used in Snohomish County. Always refer to your departments SOP/SOG’s as well as manufacturers recommendations prior to use.. Will air circulate Clockwise or Counterclockwise around each of these pressure centers?. H. L. Cyclonic and anticyclonic winds in the Northern Hemisphere. Cyclones and anticyclones . Cyclone. A center of . SCREW COMPRESSORSC-SERIESbeen synonymous with ef cient and reliable compressed air The BOGE C-series is a trendsetter in its class less noise less pipework less connections in contrast to more output EARTH SURFACE. gravity. random. motion. Weight of all air molecules is propagated to surface by random motion of molecules. Random motion of molecules causes pressure to be applied in all directions. The horizontal distribution of air pressure on the globe is studied on the basis of Isobars. If we look at the globe then it appears that there is certain definite system of high and low pressure.. If, for generalization, the globe is considered to be homogeneous (either of land or water), then there should be regular and systematic zonal distribution of high and low pressure but the regularity of pressure belts is distributed due to unequal distribution of land and water on the globe. .
