空气物性参数表
空气物性参数表湿空气热物性计算示例A●分子量Maw=Ma-(Ma-Mw)pw/paw式中，Maw为湿空气分子量，g/mol；Ma为干空气的分子量，28.97g/mol；Mw为水蒸气的分子量，18.02g/mol；pw为湿空气中水蒸气的分压力，Pa；paw为湿空气的总压力，Pa。
计算示例：设湿空气总压力为101325Pa，其中水蒸气的分压力为3000Pa，则此时湿空气的分子量为：Maw=28.97-(28.97-18.02)*3000/101325=28.65 g/mol●湿空气中水蒸气分压力pw=φps式中，pw为湿空气中水蒸气的分压力，Pa；φ为湿空气的相对湿度，无因次；ps为湿空气温度下纯水的饱和蒸气压力（也为湿空气温度下饱和湿空气中水蒸气的分压力），Pa。
纯水的饱和蒸气压力的估算式为（0～100℃）：ln(ps)=25.4281-5173.55/(Ts+273)式中，ps为水的饱和蒸气压，Pa；Ts为水的温度，℃。
计算示例：设湿空气温度为36℃，相对湿度为70%，则湿空气中水蒸气分压力的计算过程为：该温度下纯水的饱和蒸气压为：ln(ps)=25.4281-5173.55/(36+273)=8.6852ps =e8.6852=5915 Pa湿空气中的水蒸气分压力为：pw=φps=0.7*5915=4140.5Pa●湿空气的露点温度湿空气中水蒸气开始凝结的温度为其露点温度，等于其湿空气中水蒸气分压力下纯水的饱和温度，其估算式为（0～80℃）：Td=5266.77/(25.7248-ln(pw))-273式中，Td为湿空气的露点温度，℃；pw为湿空气中水蒸气的分压力，Pa。
计算示例：接上例，温度为36℃，相对湿度为70%的湿空气，其露点温度计算过程为：湿空气中水蒸气分压力为4140.5Pa，则其对应的露点温度为：Td=5266.77/(25.7248-ln(4140.5))-273=29.75℃。
