水的饱和蒸汽压力与温度的计算

1、水的饱和蒸汽压力与温度的计算。Antoine 公式：ln（P）=9.3876-3826.36/（T-45.47）【T 在 290 500K之间】P: MPaT： K经检验用此公式计算结果基本与下表数据相符，可以在PLC程序中用来作为饱和蒸汽温度的计算公式。水的饱和蒸汽压与温度对应表温度（C） td压力（Kg/cm2）td温度（C） td压力（Kg/cm2） td温度（C） td 压力（Kg/cm 2）100 td1.0332 td154 td5.397 td208 td18.690101 td1.0707 td155 td5.540 td209 td19.070102 td1.1092 td1
