测定氢气湿度的压力修正1. 目前化学运行值班人员利用现有表计所测得的氢气湿度并不是真正的发电机内的氢气湿度所对应的露点温度,而是在大气压下的氢气湿度,必须按如下方法将其修正到运行氢压下2. 已知：a 氢气湿度计测定的氢气湿度露点温度值为t1（）;b 氢气湿度计测湿元件所在处的氢气绝对压力(大气压力按0.1 MPa计)为p1(MPa);c 在氢气湿度标准中对被测对象氢气所规定的氢气绝对压力（大气压力+运行氢压）为p2;（1） 按表一,由t1查得与该露点温度值对应的饱和水蒸汽压值es1(Pa).（2） 由es1、p2和p1,按如下公式求得被测对象氢气在p2下的饱和水蒸气压值es2(Pa).es2= es1(p2/ p1)（3） 按表一,由es2查得与该饱和水蒸汽压值对应的温度值t2（）;该温度t2即为在氢气湿度标准中所规定的氢气绝对压力p2下的被测对象氢气湿度的露点温度值.（4） 例:一台发电机的运行氢气表压为0.3 Mpa,在常压下测得发电机的氢气湿度为露点温度-18.6,问此时该发电机在运行氢压下的氢气湿度为露点温度多少度?l 由题意知: t1=-18.6, p1=0.1 Mpa和p2=0.3+0.1=0.4 Mpa;l 由t1在表一中查得与-18.6对应的饱和水蒸气压es1=118.038 Pa;l 由es1、p2、p1,求得在运行氢压下的饱和水蒸气压es2=118.038*(0.4/0.1)=472.152 Pal 由es2在表一中查得与472.152 Pa对应的温度值t2=-3.1,此温度即为该发电机在运行氢压下的氢气湿度露点温度值.表一：冰的饱和水蒸气气压（0-100）
