  • Termotehnica

    La disciplina Termotehnica, transfer de caldura si masa I Intr-un cilindru obturat cu un piston mobil se introduc kg CO2, la temperatura 50C, kmol N2 la temperatura 1000C si m3N O2 la temperatura 2000C. Initial cilindrul este izolat adiabat si pistonul este mentinut fix, inchizand volumul V1= m3. Dupa formarea amestecului si atingerea starii de echilibru se inlatura izolatia, es elibereaza pistonul iar gazul descrie un ciclu format din urmatoarele transformari termodinamice: 1-2...
