Question

Carbon dioxide gas enters a water-cooled compressor at conditions P₁ = 1 bar and T₁ = 10 °C, and is discharged at conditions P₂ = 36 bar and T₂ = 90 °C. The entering CO₂ flows through a 10-cm-diameter pipe with an average velocity of 10 m⋅s⁻¹, and is discharged through a 3-cm-diameter pipe. The power supplied to the compressor is 12.5 kJ.mol⁻¹. What is the heat-transfer rate from the compressor?

H₁ = 21.71 kJ.mol⁻¹ V₁ = 23.40 L.mol⁻¹

H₂ = 23.78 kJ.mol⁻¹ V₂ = 0.7587 L.mol⁻¹

P2=36 bar
W = 12.5 kJmol1
Comp.
P1=1 bar
