Lo lus "polytropic" yog thawj zaug los piav qhia txhua txoj kev thim rov qab ntawm txhua qhov qhib lossis kaw ntawm cov pa roj lossis vapor uas cuam tshuam txog kev hloov pauv thiab ua haujlwm, xws li cov lus teev tseg kev sib xyaw ntawm cov khoom tau khaws cia tas mus li thoob plaws hauv cov txheej txheem.
Puas yog tag nrho cov txheej txheem polytropic thim rov qab?
Polytropic txheej txheem yog sab hauv thim rov qab. Qee qhov piv txwv yog vapors thiab cov pa roj zoo tag nrho hauv ntau cov txheej txheem tsis ntws, xws li: n=0, ua rau P=tas li xws li txheej txheem isobaric.
Koj ua li cas xam cov txheej txheem polytropic?
Cov Txheej Txheem Polytropic tuaj yeem txhais tau tias yog cov txheej txheem uas cov cua sov nqus los ntawm cov pa vim qhov ntsuas kub ntawm chav nyob tas li. Cov txheej txheem polytropic yog txheej txheem thermodynamic uas tuaj yeem qhia tau siv cov kab zauv hauv qab no. PV =C, Nws yog kev sib npaug ntawm cov txheej txheem Polytropic.
Puas yog txheej txheem isentropic ib txwm thim rov qab?
A reversible, adiabatic txheej txheem yog ib txwm isentropic txij thaum tsis muaj entropy tiam vim irreversibilities (sgen=0) thiab tsis muaj kev hloov ntawm entropy vim tshav kub hloov (ds=? … Q /T=0).
