Question

Using your sling psychrometer, take readings outside to determine the following: 1) dry-bulb temperature (degrees C) 2) dry-bulb temperature (degrees F) 3) final wet-bulb temperature (degrees C) 4) final wet-bulb temperature (degrees F) 5) wet-bulb depression (degrees C) 6) wet-bulb depression (degrees F) 7) dew point temperature (degrees C) 8) dew point temperature (degrees F) 9) dew point depression (degrees C) 10) dew point depression (degrees F) 11) relative humidity (percent) you measure this stuff outside with the proper weather equipment.

Explanation / Answer

While this experiment must be done practically, an example of the above readings from San Francisco can be given as follows:

1 Dry Bulb Temp (C): 17.7

2 Dry Bulb Temp (F): 63.86

3 Wet Bulb Temp (C): 28.6

4 Wet Bulb Temp (F): 83.48

5 Wet Bulb Depression (C): 10.9

6 Wet Bulb Depression (F): 19.62

7 Dew Point Temperature (C): 7.78

8 Dew Point Temperature (F): 46

9 Dew Point Depression (C): will depend on location

10 Dew Point Depression (F): will depend on location

11 Relative Humidity (%): 68
