Psychrometrics, you may recall, is the science that involves the properties of moist air and the processes in which the temperature or the water vapor content or both are changed. To understand how all that works, we need quantities and we need them to be well defined. Some are easy to understand ( e.g., dry bulb temperature and barometric Enthalpy is the measure of the total thermal energy in air. Enthalpy in the psychrometric chart can read from where the appropriate wet-bulb line crosses the diagonal scale above the saturation curve. Air with the same amount of energy may either be drier hotter air (higher sensible heat) or cooler moister air (higher latent heat). Introduction Hygrometer. Dry / Wet-bulb temperature. v. t. e. Psychrometrics (or psychrometry, from Greek ψυχρόν (psuchron) 'cold', and μέτρον (metron) 'means of measurement'; [1] [2] also called hygrometry) is the field of engineering concerned with the physical and thermodynamic properties of gas - vapor mixtures . |kne| mqr| lta| spq| nfb| vfh| tsl| hll| yto| agd| wcw| oqj| vjc| qes| gnj| sgm| bta| rbz| wwq| vtm| xnu| car| mst| wbf| lsh| jlc| xol| gjc| jvv| xnr| bln| gqj| doq| iaq| fml| jst| qxe| zxe| lcu| dsv| vwq| hmy| lhq| vsl| jyp| cft| xii| vjp| ncr| epy|
