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(shí)我們也經(jīng)常會(huì)提到1.6mpa壓力、2.5mpa壓力和多少公斤壓力、多少個(gè)標(biāo)準(zhǔn)大氣壓等之類的術(shù)語(yǔ),那么1mpa壓力到底有多大壓強(qiáng),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(qiáng),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(biāo)準(zhǔn)帕斯卡(1pa=1n/m2)
1公斤力/平方厘米=98.0665千帕
粗算時(shí)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(qiáng),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(gè)手指頭上所產(chǎn)生的壓強(qiáng)。 我們來(lái)計(jì)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(jì)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(qiáng),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(shuō)明: pa,壓強(qiáng)單位,中文名稱為“帕斯卡”,簡(jiǎn)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(wàn) n,物理力學(xué)單位,簡(jiǎn)稱牛,是一種衡量力的大小的單位,兩個(gè)雞蛋的重力約為1n(0.1千克的物體的重量) m,長(zhǎng)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
