aerul umed si marimi caracterisitice


Prin aer umed se intelege amestecul dintre vaporii de

apa si aerul uscat. Vaporii de apa dintr-un amestec exrcita o presiune,

numita presiunea partiala avaporilor de apa, notata cu pv

sau e. Cu ecuatia lui Dalton, se pesupune ca intr-un gram de aer umed

ar fi aer uscat si vapori de apa la aceeasi temperatura, cu volume

specifice , ecuatia de stare petru vapori ar fi:






pvV=RT/μv




Presiunea partiala a vaporilor de apa din aerul umed

saturat se numeste presiune de saturatie ( de echilibru).Depinde de

temperatura suprafetei evaporante, de de faza in care se afla apa.


Starea de saturatie a unei mase de aer se defineste prin umiditatea

relativa, adica raportul dintre presiunea reala a vaporilor si

presiunea maxima a vaporilor functie de temperatura la care se afla

aerul umed. Racirea contiua a aerului duce la cresterea umiditatii

relatie si apoi la saturatie. Pentru o temperatura T, presiunea maxima

a vaporilor in raport cu apa este mai mare decat cea in raport cu

gheata, deci aerul saturat in raport cu apa este suprasatruat in raport

cu gheata.


Umiditatea relativa: U=100 pv/pvs




Umiditatea absoluta: cantitatea de vapori, in grame, din unitatea de volum de aer , ρv




Umiditatea specifica: cantitatea in grame de vapori de apa din g(kg) de aer umed, sau raportul dintre densitatea vaporilor si cea a aerului umed:  q=ρv/ρ


Raportul de amestec (coeficientul amestecului)

cantitatea de vapori in grame, asociata gramului de aer uscat, sau

raportul dintre densitate vaporilor de apa si densitatea aerului uscat:

r=
ρva
