American Society of Heating and Ventilating Engineers Guide, 1930 temperature, dew-point temperature, and dew-point differentials for 50 per cent relative humidity illustrates this relationship most clearly: Dry-bulb temperature.............. ................ 65.0 Dew-point temperature................................... 45.8 Difference between dew-point and drybulb temperature........................................ 19.2 70.0 50.5 19.5 75.0 80.0 85.0 90.0 55.25 59.75 64.25 68.75 \ 19.75 20.25 20.75 21.25 It will be seen from an inspection of this table that the difference between the dew-point temperature and the room temperature is approxi mately 20 deg. throughout this range of dry-bulb temperatures or, to be more exact, the differential increases only 10 per cent for a range of practically 25 deg.
