Integration of Thermodynamics equation w=–∫vDP

Click For Summary
SUMMARY

The discussion focuses on integrating the thermodynamic equation w=–∫vDP from state 2 to state 1, resulting in the expression k(P2V2-P1V1)/(1-k). This equation is applicable for steady flow processes involving reversible and ideal gases. Participants emphasize the importance of understanding the relationship between enthalpy change (dH) and the variables involved, specifically noting that dH=C_pdT=VdP is a crucial step in the integration process.
