공기의 물성치(material property of air)
Air is a mixture of gases, 78% nitrogen and 21% oxygen with traces of water vapor, carbon dioxide, argon, and various other components. We usually model air as a uniform (no variation or fluctuation) gas with properties that are averaged from all the individual components. 출처 http://www.engineeringtoolbox.com/air-composition-d_212.html Tistory 태그: air,공기 물성치,material property air
