Turbomachinery Maps: axial_compressor_90
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 | head coefficient | is choke point | is surge point | isentropic efficiency pct (%) | machine type | notes | power coefficient | speed pct (%) | surge margin pct (%) | work coefficient |
