Question #3 40 Marks A device within a piston - cylinder assembly undergoes three processes in series: Process 1-2: compression at constant pressure from p₁-70 kPa, V₁=0.11 m³ to state 2. Process 2-3: constant volume heating to state 3, where p3-350 kPa. Process 3-1: expansion to initial state, during which the pressure- volume relationship is pV=constant. (a) Sketch the processes (cycle) on p-V coordinates to scale (Use graph paper); [20 Marks] (b) The volume at state 2, in m³ [5 Marks] (c) The work for each process, in kJ. [10 Marks] (d) Is this a power cycle or a refrigeration cycle? [5 Marks]
