在截止閥管件行業(yè)中,根據(jù)公稱壓力PN的大小,我們可以把公稱壓力小于等于1.6MPa的閥門為低壓閥門,公稱壓力為2.5MPa、4.0MPa、6.4MPa的閥門為中壓閥門,同時我們也經(jīng)常會提到1.6MPa壓力、2.5MPa壓力和多少公斤壓力、多少個標準大氣壓等之類的術(shù)語,那么1MPa壓力到底有多大壓強,1MPa壓力等于多少公斤壓力呢蒸汽壓力為2.5㎏是表示2.5kg/cm2,是表示的單位面積上的壓力--壓強,通常俗稱為2.5kg壓力。新的表示方法約為0.25MPa。
換算關(guān)系:1kg/cm2=0.098MPa,因此壓力2.5kg/cm2=0.245MP,可約等于0.25MPa.ISO標準帕斯卡(1Pa=1N/m2)
1公斤力/平方厘米=98.0665千帕
粗算時常按1公斤力=10N 則:
1公斤力/平方厘米=100千帕=1bar=0.1MPa
10公斤力/平方厘米=1000千帕=1MPa
公斤的單位是質(zhì)量單位
MPA是壓力的單位
質(zhì)量m=壓力/重力加速度
壓力p=壓力/面積
這是他們之間的關(guān)系
1公斤壓力指的是1公斤重的物體作用為1cm2面積上所產(chǎn)生的壓強,可以想像一下,1公斤重(比兩瓶一元錢的康師傅礦泉水重略輕)的物體全部壓在一個手指頭上所產(chǎn)生的壓強。 我們來計算一下, 1MPa=1×106Pa 1Pa=1N/1m2 1MPa=106N/m2=106N/104cm2=100N/cm2 重力加速度g約等于9.8 N/KG,為方便計算,g按整數(shù)10。 1KG的物體重力=1KG×10N/KG=10N 1公斤壓力是1KG的重力作用于1cm2面積上產(chǎn)生的壓強,即 1公斤壓力=10N/cm2 1MPa=100N/cm2=10×10N/cm2 即1MPa壓力等于10公斤壓力。
單位說明: Pa,壓強單位,中文名稱為“帕斯卡",簡稱“帕",即牛/平方米,1帕=1牛/平方米 M,數(shù)量單位,M即million,數(shù)值為一百萬 N,物理力學單位,簡稱牛,是一種衡量力的大小的單位,兩個雞蛋的重力約為1N(0.1千克的物體的重量) m,長度單位,米 m2,面積單位,平方米 cm2,面積單位,平方厘米 KG,重量單位,千克,公斤
