surroundings.Thus, after a time, the wet thermometer willindicate a temperature constantly below thatof the dry one by an amount depending onthe humidity, since the rate of evaporationis determined by the amount of aqueousvapor present in the atmosphere. In order to deduce the dew point from the… … Fig. 168. EXAMPLES. 243 In dry weather, or when the air is quite still, the dewpoint, as deduced from observation of the wet and dry bulbthermometer, is usually a little high, probably because theseconditions favor the elevation of the temperature of the wetthermometer by radiation from surrounding…
