Turbomachinery Maps: centrifugal_pump_80
Turbomachinery performance maps — compressor, turbine, fan, pump, and turbocharger characteristic curves showing efficiency, pressure ratio, head coefficient, and surge/choke boundaries at various speeds and flow rates
| machine speed | flow pct | flow coefficient | is choke point | is surge point | isentropic efficiency pct (%) | machine type | notes | speed pct (%) |
|---|---|---|---|---|---|---|---|---|
| centrifugal_pump_80 | 100 | 0.16 | false | false | 84.5 | centrifugal_pump | 100% design flow at 80% speed; head significantly below system curve at design flow; pump under-delivers | 80 |
| centrifugal_pump_80 | 30 | 0.048 | false | false | 74 | centrifugal_pump | Very low flow pump 80% speed; affinity law: head scales as N^2; H_80 = 0.64*H_100 at any phi | 80 |
| centrifugal_pump_80 | 40 | 0.064 | false | false | 78.5 | centrifugal_pump | Low flow pump 80% speed; affinity laws apply closely for geometrically similar operation | 80 |
