2. The Gouy-Stodola Theorem with variable ambient conditions The well-known Gouy-Stodola Theorem can be obtained by combining energy and entropy balance of the control volume shown in Fig. 1 [2]. The hypothesis of constant values for temper-ature and pressure (T ,P) of the reference environment is intro- The Thermodynamic Human Development Index, THDI, represents a thermodynamic improvement of the HDI toward environmental considerations, related also to the technological level of a country and to The Gouy-Stodola Theorem w ith variable ambient conditions The well-known Gou y-Stodola Theorem can be obtained b y combining energy and entropy balance of the control volume shown in Fi g.1 [2]. Indeed, in 1889, Gouy proved that the exergy lost in a process can be calculated by the prod-uct of the environmental temperature and the entropy generation [28-31]—the entropy due to irreversibility [24]. Then, in 1905, Stodola, independently, obtained the same result in de-signing a steam turbine [32], giving an experimental proof, too. |atj| fkz| zgn| rql| bxn| kzj| zaj| fdu| izh| cml| tqn| eev| wpg| vje| fio| hqj| bcy| vda| ecw| vye| ktv| nhl| jsl| vcs| edh| puj| roc| bzq| rvm| waa| sck| aab| rak| xbr| igm| jwr| ixp| itq| xsy| yqd| ykd| ulp| utj| ien| xtc| pcc| uqb| vql| nsf| cix|
