Compressor Mass Flow Annular Area

Given the mass flow rate through a compressor rotor inlet and the annular mass flux (mass flow per unit area), calculate the required annular flow area at the rotor inlet. This is essential for determining blade geometry and ensuring proper stage matching.

✓ All 2 test cases pass.

Inputs

Mass flow rate

Total mass flow through the compressor inlet (kg/sec)

Annular mass flux

Mass flow per unit annular area (kg/sec·m²)
