四、水蒸气的h-s图
一、定压线 ：dqp = dh， dq = T.ds， h
h T s p
C
X=1
定压预热阶段：向上凹曲的曲线；
定压汽化阶段：直线；
定压过热阶段：上凹曲的曲线。
s
二、定温线 ：在湿蒸汽区定压线就是定温线，因而定温线在湿蒸汽 区为直线；在过热蒸汽区为向右凸曲的曲线， 越往右，定温线越 趋于水平。

饱和水蒸汽压力温度对照表
饱和水蒸汽压力温度对照表
在实际应用中，这个表格可以用于计算和预测饱和水蒸汽的行为。
例如，在暖通空调系统中，这个表格可以帮助工程师计算在给定温度下系统中的水蒸汽压力，进而帮助确定制冷或制热的需求。
这个表格是基于理想气体定律以及一些工程近似计算得出的。
然而，在某些特定情况下，实际压力可能会与这个表格中的数据存在些许偏差，特别是在压力和温度都较高或较低的情况下。
因此，在使用这个表格时，应当结合实际情况和专业知识进行适当的修正和调整。
