6.5 Irreversibility, Entropy Changes, and ``Lost Work

WebDefine a thermodynamic process. Distinguish between quasi-static and non-quasi-static processes. Calculate physical quantities, such as the heat transferred, work done, and internal energy change for isothermal, adiabatic, and cyclical thermodynamic processes. In solving mechanics problems, we isolate the body under consideration, analyze the ... WebAdiabatic, irreversible processes between the same initial state and final volume always yield lower work. This is a useful criterion to determine when an adiabatic process is irreversible: • The process is reversible if dU + p · dV = 0. • The process is irreversible if dU + p · dV > 0. • The process is not feasible if dU + p · dV < 0. WebFour of the most common causes of irreversibility are friction, unrestrained expansion of a fluid, heat transfer through a finite temperature difference, and mixing of two different substances. These factors are present in real,irreversible processes and prevent these processes from being reversible. Link to this Webpage: Engineers Edge: dynamics toast notification
