A three-stage air compressor has the following stage pressure ratios and adia- batic efficiencies: Stage 123 2 3 Stagnation Pressure Ratio 1.6 1.4 1.3 Adiabatic Efficiency 0.87 0.89 0.90 What are the compressor pressure ratio and the overall adiabatic efficiency? What is the average polytropic efficiency? If the stage temperature ratios and adiabatic efficiencies had been uniform through the stages and the overall temperature ratio the same as above, by how much would the stage efficiency have differed from the polytropic efficiency?
Step by Step Solution
