问题：饱和蒸汽温度与压力对照表
说明：
蒸汽是常用的换热介质，而温度控制是通过一定压力下的流量调节来实现的，希望大家建立一个基本的概念。在热交热器或者其它需要蒸汽阀门的地方，大家在选型时经常会用到。 

现将饱和蒸汽的温度与压力对照表整理，供大家参考！

可以说对的,10公斤绝对大气压对应的饱和蒸汽温度就是179度,楼上的说的184度是10公斤表压(也就是压力表上指示的压力;压力表是从0开始记数的,而大气本身就有1公斤的压力，绝对大气压=表压+1),184度是11公斤绝对大气压下的饱和蒸汽对应温度。这里都强调“饱和蒸汽”，因为还有“过热蒸汽”，过热蒸汽的温度是不于压力成对应关系的。

Antoine公式: ln(P)=9.3876-3826.36/(T-45.47)【T在290～500K之间】 

P：MPa 

T：K 

我用这个公式算出来是T=452.77K 约179度.

不知道对不对?请高手指教!

    加热室温度差=壳层压力(真空度)相应温度-加热室料液温度

    蒸汽过热度=蒸汽温度-饱和蒸汽压力相应温度

 

压力单位非常的多,如果要全部写出来……呵呵,我还做不到，我至今也没都认识全,不过有很多很少使用。主要还是学习国际单位和几个常用单位就可以了。

常用压力单位有： 

帕斯卡N/m2（Pa） 千帕(kPa) 兆帕(MPa) 

巴（bar） 毫巴（mbar）微巴（μbar） 

标准大气压（atm） 

磅力/英寸^2 lb/inch2（psi) 

工程大气压(kgf/cm2) 

托（Torr）=毫米汞柱（mmHg） 

英寸汞柱（inchHg） 

毫米水柱（mmH2O） 

达因/厘米2（dyn/cm2） 

换算关系：

1兆帕(MPa)＝1000000帕(Pa)

 巴(bar)＝1000毫巴(mbar) 

 毫巴(mbar)＝1000微巴(μbar)＝1000达因/厘米2(dyn/cm2) 

 托(Torr)＝1毫米汞柱(mmHg)＝133.329帕(Pa) 

 工程大气压＝1千克力/厘米2(kgf/cm2)

 物理大气压＝1标准大气压(atm)
