Bulb thermometer definition
WebThe liquid-in-glass thermometer is a well-known temperature-measuring instrument that is used in a wide range of applications, although there is a growing trend to use a digital thermometer instead. The fluid used in the thermometer is normally either mercury or colored alcohol contained within a bulb and capillary tube, as shown in Fig. 14.18A . The dry-bulb temperature (DBT) is the temperature of air measured by a thermometer freely exposed to the air, but shielded from radiation and moisture. DBT is the temperature that is usually thought of as air temperature, and it is the true thermodynamic temperature. It is directly proportional to the mean kinetic energy of the air molecules. Temperature is usually measured in degrees Celsius

WebThe meaning of CLINICAL THERMOMETER is a thermometer for measuring body temperature that has a constriction in the tube above the bulb preventing movement of the column of liquid downward once it has reached its maximum temperature so that it continues to indicate the maximum temperature until the liquid is shaken back down into …
WebThe meaning of DRY-BULB THERMOMETER is an ordinary thermometer; specifically : the thermometer with unmoistened bulb in a psychrometer. WebMar 18, 2014 · Operative Temperature and Thermal Comfort. Operative temperature is calculated based on air temperature (dry bulb), mean radiant temperature (MRT), and air velocity. At air velocities below 40 fpm, it is the average of MRT and air temperature. MRT basically is a weighted average of the surface temperatures surrounding an occupant.
WebApr 1, 2024 · What is Wet Bulb Temperature? When water evaporates into the air it creates a cooling effect, but the amount of this cooling varies depending on the overall air temperature and the relative humidity. The wet-bulb temperature is the lowest possible temperature that air can be cooled down to by the evaporation of water alone, given … WebA dry bulb thermometer to measure the ambient air temperature. A natural wet bulb thermometer to measure the potential for evaporative cooling. A black globe thermometer to measure radiant heat. The …
