Further calculations of water volume in the gas involved calculation of the dry fraction or percentage of water in the gas stream. To make this calculation the water vapor fraction when the gas is saturated with water vapor is needed. This value is determined using saturation tables and for 152 degrees F the saturated fraction is 0.267 or 26.7 .
