An ideal gas in a heat engine undergoes the following processes comprising a cycle in a pistoncylinder
Question:
An ideal gas in a heat engine undergoes the following processes comprising a cycle in a piston–cylinder regenerator device:
1–2: isothermal heating at TH from a heat source at TH,
2–3: constant-volume cooling to TL by the regenerator,
3–4: isothermal cooling at TL by a heat sink at TL, and
4–1: constant-volume heating to TH by the regenerator.
A. Determine the thermal efficiency for the heat engine by considering the work and heat flow for each process.
B. Is the heat engine reversible? Why? Explain.
