  • EMT dew point value

    EMT dew point value. Apr 10, 2018The dew-point temperature is at the intersection of the design dry bulb temperature column and relative humidity row. For this example, the dew point temperature is 65F. Note: If the design values don't exactly match the values in the chart, you can use linear interpolation to determine the dew point temperature.
