Problem 1 An ideal gas, Cp= (7/2)R and Cy=(5/2)R, undergoes a cycle consisting of the follow- ing mechanically reversible steps: An adiabatic compression from Pj, Vị, T¡ to P2, V2, T2. An isobaric expansion from P2, V2, T2 to P3 = P2, V3, T3. • An adiabatic expansion from P3, V3, T3 to P4, V4, T4. A constant-volume process from P4, V4, T4 to P1, V1 = V4, T1. Sketch this cycle on a PV diagram and determine its thermal efficiency if T¡ = 200°C, T2 = 1000°C, and T3 = 1700°C.

Answer completely with a diagram.

Problem 1 An ideal gas, Cp= (7/2)R and Cy=(5/2)R, undergoes a cycle consisting of the follow- ing mechanically reversible steps: An adiabatic compression from P1, Vị, T¡ to P2, V2, T2. • An isobaric expansion from P2, V2, T2 to P3 = P2, V3, T3. An adiabatic expansion from P3, V3, T3 to P4, V4, T4. A constant-volume process from P4, V4, T4 to P1, Vị = V4, T1- Sketch this cycle on a PV diagram and determine its thermal efficiency if T1 = 200°C, T2 = 1000°C, and T3 = 1700°C. ret deri ve this.
