饱和水蒸汽压力与温度、密度、蒸汽焓、气化热的关系对照表 一.什么是水和水蒸气的焓? 水或水蒸气的焓h，是指在某一压力和温度下的1千克水或1千克水蒸气内部所含有的能量，即水或水蒸气的内能u与压力势能pv之和(h=u+pv)。水或水蒸气的焓，可以认为等于把1千克绝对压力为兆帕温度为0℃的水，加热到该水或水蒸气的压力和温度下所吸收的热量。焓的单位为“焦/千克”。 (1)非饱和水焓：将1千克绝对压力为兆帕温度为0℃的水，加热到该非饱和水的压力和温度下所吸收的热量。 (2)饱和水焓：将1千克绝对压力为兆帕温度为0℃的水，加热到该饱和水的压力对应的饱和温度时所吸收的热量。饱和温度随压力增大而升高，因此饱和水焓也随压力增大而增大。例如：绝对压力为兆帕时，饱和水焓为 x 103焦/千克;在绝对压力为兆帕时，饱和水焓则为 x 103焦/千克。 (3)饱和水蒸气焓：分为干饱和水蒸气焓和湿饱和水蒸气焓两种。干饱和水蒸气焓等于饱和水焓加水的汽化潜热；湿饱和水蒸气焓等于1千克湿饱和蒸汽中，饱和水的比例乘饱和水焓加干饱和汽的比例乘干饱和汽焓之和。例如：绝对压力为兆帕时，饱和水焓为 x103焦/公斤；汽化潜热为1328 x103焦/公斤。因此，干饱和水蒸气的焓等于： x103+1328x103= x 103焦/千克。又例如:绝对压力为兆帕的湿饱和水蒸气中，饱和水的比例为,(即湿度为20%)干饱和水蒸气比例为(即干度为80%)，则此湿饱和水蒸气的焓为 x103 x 十 = x 103焦/千克。 (4)过热水蒸气焓：等于该压力下干饱和水蒸气的焓与过热热之和。例如：绝对压力为兆帕，温度为540℃的过热水蒸气的干饱和水蒸气的焓为 x 103焦/千克，过热热为 x 103焦/千克。则该过热水蒸气的焓为: x 103+ x 103= x 103焦/千克。
