... is 1 ,50 0 psia, a 4-stage compressor with a 3.2 compression in each stage might be used. The pressure at the discharge of each stage would be: 1st 5 47 psia, 2nd 51 50 .5 psia, 3rd 5 481.7, ... 481.7, 4th 5 1 ,54 1.4 psia. The simple calculation used to calculate the pressure increase on each stage is:Stage One 14.7 psia 3 3.2 5 47.04 psiaStage Two 47.04 psia 3 3.2 5 150 .52 8 psiaStage ... 150 .52 8 psiaStage Three 150 .52 8 psia 3 3.2 5 481.689 psiaStage Four 481.689 psia 3 3.2 5 154 1.407 psiaThe basic components of a centrifugal compressor are shown in Figure 5. 2.
