Rotor Inlet Tip Speed To Annular Flow

Given the mass flow rate through a compressor rotor inlet and the annular flow density (mass per unit area per unit time), calculate the effective annular area at the rotor inlet.

✓ All 2 test cases pass.

Inputs

Mass flow rate

Total mass flow through the rotor inlet in kg/sec

Annular flow density

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