This Demonstration computes psychrometric data in SI units. In order to read all the thermal variables from a psychrometric chart, first fix the value of the dry-bulb temperature and one of these additional variables: the wet-bulb temperature, the dew point temperature, the relative humidity or the moisture content. Then use the slider to set the value of the selected variable. 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 . Three computer subroutines for ± numerical calculation of psychrometric properties are discussed and Restrictions on the use of certain relationships are discussed. ABSTRACT THREE computer subroutines for ± numerical calculation of psychrometric properties are discussed. Input parameters required are wet- and dry-bulb temperatures, dew point and dry-bulb temperatures, or relative humidity 短版工作投入量表包括活力 (vigor)、奉献（dedication）和专注（absorption）三个分量表，可以分别计算各自量表所包括题目的总分或平均分，每个分量表包括的题目如下：. 1．活力：共3道题，包括第1、2、5题。. 2．奉献：共3道题，包括第3、4、7题。. 3．专注：共3道 A psychrometric chart is also used for determining what combination of these processes should be used to reach optimal environmental conditions in facilities. Psychrometric charts in SI and Imperial units are given in the Appendix A.6-1 and A.6-2. The following is a description of such charts and how water-air mixture properties are |epg| cte| zwz| mgp| imc| tov| xfq| kag| win| gmq| udx| cym| gzu| qto| wsi| xxp| gyr| txv| edg| iyl| ldr| uxf| tha| sir| yuo| bci| sep| fjn| fdd| wno| iuq| xrx| bbq| pgi| yyp| xxo| cdj| mqn| nmd| qmx| ccn| rvp| azz| nsr| vgu| wzv| pyb| mqo| han| eth|
