What is the dew point of an SF6 system having a moisture content of 300 PPMV at guage pressure 152 kPa (22psig) Pressure = 300 * 10 -4 (22 + 14.7) 51.7 = 0.57mmHg. The 51.7 multiplier is used to convert the pressure from psia to mmHg for use with Table :1. (760 mmHg = 14.7 psi, so 1 psi = 760/14.7 = 51.7 mmHg)
