Turbomachinery Maps: centrifugal_fan_60
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_fan_60 | 100 | 0.15 | false | false | 66 | centrifugal_fan | Full design flow at 60% speed; very low static pressure; minimum practical VFD operating speed for most systems | 60 |
| centrifugal_fan_60 | 30 | 0.045 | false | false | 50 | centrifugal_fan | Very low flow fan 60% speed; head ~36% rated; marginal static pressure for most HVAC duct systems | 60 |
| centrifugal_fan_60 | 40 | 0.06 | false | false | 58.5 | centrifugal_fan | Low flow fan 60% speed; efficiency rising; efficiency lower than higher speeds due to Re effects | 60 |
