Question
A power cycle consisting of the three processes:
Process 1-2: Constant volume to P2
Process 2-3: Polytropic expansion Pv=c, use k=1.28
Process 3-1: Compression at constant pressure
Assuming 2.5 kg carbon dioxide as the working substance with P₁= 1.5 bar,
P₂= 6 bar, T₁=350 K and neglecting kinetic and potential energy effects:
a) sketch cycle in P-v diagram
b) calculate thermal efficiency
CO₂ molar mass = 44.
CO₂ specific heat cy=1.014 kJ/kg/K
