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
psychrometer - a hygrometer consisting of a dry-bulb thermometer and a wet-bulb thermometer; their difference indicates the dryness of the surrounding air. dry-bulb thermometer - an ordinary thermometer with a dry bulb; used to measure the air temperature. hygrometer - measuring instrument for measuring the relative humidity of the atmosphere. wet-bulb thermometer - a thermometer with a bulb that is covered with moist muslin; used in a psychrometer to measure humidity.
