Fundamental of Thermodynamics & Heat Transfer

An ideal gas undergoes a thermodynamic cycle consisting of the following three processing in series. Process 1-2: constant volume, V₁ = 0.1 m³, P₁ = 100 kPa, U₂-U₁ = 150 kJ. Process 2-3: expansion with PV = constant. Process 3-1: constant pressure, W₃₁ = -60 kJ. (a) Sketch the process on P-V and T-V diagram. (b) Calculate network for the cycle. (c) Calculate net heat for the cycle. (d) Calculate the heat transfer for the process 1-2. (e) Calculate the heat transfer for the process 2-3. (f) Calculate the heat transfer for the process 3-1. (g) Is this power cycle or a refrigerator cycle?
