Identification of Ungrounded Conductors. Today John Hauck and David Burtt discuss the identification of ungrounded conductors according to the 2011 National Electrical Code. This is part 1 of a 3 part series on identifying conductors.
The wet-bulb temperature is the temperature a parcel of air would have if it were cooled to saturation by the evaporation of water into it, with the latent heat being supplied by the parcel. A wet-bulb thermometer will indicate a temperature close to the true wet-bulb temperature. The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only. Wet-bulb temperature is largely determined by both actual air temperature and th
Interpretation: The bigger the difference between the temperature of the air and the wet-bulb temperature, the relatively drier the air must be. Hence, the difference between the temperature and the wet-bulb temperature is a measure of how close to saturation the air is.We can measure the wet-bulb temperature and the air temperature using a sling psychrometer (demonstrated in class).Using tables such as those in Appendix D of your textbook, we can use these measurements to look up the relative humidity and the dew-point temperature.nterpretation: The bigger the difference between the temperature of the air and the wet-bulb temperature, the relatively drier the air must be.
