Pressure Science and Technology Definition of Terms
Chinese name: English name pressure: atmospheric pressure Definition 1: atmospheric pressure. Unit cross-sectional area is usually exposed on the weight of said vertical column. Respective disciplines: atmospheric science (a subject); atmosphere (two subjects) Definition 2: atmospheric pressure. Unit cross-sectional area is usually the vertical column on the weight of exposure, said. Respective disciplines: Fisheries (one subject); Fisheries basic science (two disciplines)
The definition of a gas pressure in any unit area on the surface of the air pressure generated by molecular motion. p = F / S 2, air pressure per unit area is the role of atmospheric pressure, that is equal to the unit area extends upward into the atmosphere on the upper bound of the weight of the vertical column of air. Pressure in hPa (hPa) as a unit, one decimal place. International System unit: Pascal, called Pascal, symbol Pa. Common unit: standard atmospheric pressure. Said pressure unit, customarily used mercury column height. For example, a standard atmospheric pressure is equal to 760 mm high weight of mercury, which is equivalent to the pressure on one square centimeter area of 1.0336 kg heavy atmospheric pressure. As countries of weight and length of different units, air units are not uniform and therefore, this does not facilitate a comparative analysis of the global pressure. Therefore, the international harmonization of the provisions of "hPa" as the pressure unit. After conversion: a standard atmospheric pressure = 1013 hPa (mbar) 1 mm mercury (Hg) column height = 4 / 3 hPa (mbar) 1 atm = 760mm of mercury (Hg) column height.

㈡ 塑鋼門窗氣壓平衡口有什麼作用在什麼位置打口

塑窗的氣壓平衡孔主要起的作用是，窗型材的玻璃腔內的氣壓和室外氣壓相同，防止雨水內灌，讓水汽排到室外。氣壓平衡孔一半是在玻璃的上部，而排水孔要在玻璃的下部。南方雨水多的地區是要重視該結構的。

㈢ 塑鋼窗窗扇用設排水孔或叫氣壓平衡孔嗎塑鋼窗死玻璃用設排水孔嗎有什麼依據大家幫忙一下

原則上，塑鋼窗扇的排水孔是為了解決因膠條密封材料密封性能不強，產生的雨水灌入內腔。排水進行到室外的過程。主要是緩解大雨或暴雨的天氣，造成雨水灌入室內產生的影響。這是排水孔設計的最初理念和想法。
現在很多廠家解釋排水孔為氣壓平衡孔，因為室外風壓較大的時候，因為室內外氣壓的不同，會對塑鋼窗的變形產生較大的影響。增加了平衡孔，可以緩解氣壓對窗戶的瞬時沖擊，有利於窗戶的整體穩定性和耐久性。
死玻璃也要排水孔。這個你可以參考國際標准。GB8814.這個是塑鋼標准，排水孔的設計嚴格執行國際標准。

㈣ 塑鋼門窗氣壓平衡口有什麼作用在什麼位置打口

在開啟扇合頁邊抄上合頁下方.開啟扇和框間隙內.
讓水能夠順利的通過排水孔排到室外去.
當室外刮風下雨的時候氣壓有有變化,扇框密封腔的氣壓不變的話,進入到該腔的雨水很難排出,將該腔與室外連通,則更有利於雨水排出.
希望對你有幫助.

㈤ 塑鋼門窗氣壓平衡口有什麼作用在什麼位置

塑門窗氣壓平衡孔的作用是玻璃壓線的空腔內的氣壓和室外氣壓平衡，使雨天不至於漏雨進去，位置在上部不易進水的地方。
