蒸汽温度压力对照表
根据1MPa=1000kPa=10.2kgf/cm2（kg/cm2），通过与饱和蒸气压（单位为MPA）和蒸汽标准表的比较，可以计算出饱和蒸气压（kgf/cm2）与蒸汽温度的关系。温度如下：饱和蒸汽的温度和压力之间只有一个自变量。理想饱和蒸汽状态是指温度、压力和蒸汽密度之间存在一一对应关系。如果其中一个已知，其他两个值为常量。有此关系的蒸汽为饱和蒸汽，有饱和蒸汽压力和温度的对照表。饱和蒸汽压力与蒸汽温度标准对照表按国际单位制编制，压力单位为兆帕，温度单位为摄氏度。 扩展数据 测量饱和蒸气压有两种方法 1动态方法。测定液体在不同外压下沸点的方法，又称沸点法。这种方法只能测量接近大气压的饱和蒸气压，精度高。 2静态法。它是指直接测量液体在不同温度下的饱和蒸气压，即在恒定温度下测量饱和压力。静态方法相对简单，用途更广。通常的方法是将被测材料置于密闭容器中，使其处于
气液共存状态，然后放入恒温槽中。通过调节恒温槽的温度，可以测量不同温度下的饱和蒸气压数据。 在封闭条件下，在一定温度下，与固体或液体平衡的蒸气压称为饱和蒸气压。饱和蒸汽压力也称为蒸汽压力。同一种物质在不同的温度下有不同的蒸气压，并且随着温度的升高而增加。对于同一种物质，固体的饱和蒸气压低于液体的饱和蒸气压。 饱和蒸汽是指由于气体分子之间的热运动而处于饱和状态的蒸汽。当液体在有限的封闭空间内蒸发时，液体分子通过液体表面进入上层空间，成为蒸汽分子。因为蒸汽分子处于湍流热运动中，它们相互碰撞。蒸汽压力与饱和蒸汽温度之间存在对应关系，不同压力下存在一定的饱和温度。换言之，在一定的压力下，水完全蒸发并继续吸收热量，但直到温度开始升高，温度才上升，变成饱和蒸汽。

饱和水蒸汽压力与温度密度蒸汽焓汽化热的关系对照表
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。
