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
The lowest temperature that can be reached by evaporating water into the air. Note: the wet bulb temperature will always be less than or equal to the temperature. Example: If you are a runner: T = 90F, RH = 90% => high wet-bulb temp. T = 90F, RH = 10% => low wet-bulb temp. feel more comfortable when wet-bulb temperature is low.
