The Stanitz slip factor is best applied for radial vanes and with β2 = 0
By Euler’s pump is best applied for radial vanes and with β1 = 0
Mollier chart for a centrifugal compressor
Overall pressure ratio versus impeller tip speed (from Eq. (4.12)
Equation (4.11) can be written in terms of fluid properties and flow angles as follows since
INLET VELOCITY LIMITATIONS
Optimization of the mass flow function
Therefore, for a gas of known inlet stagnation conditions (e.g. the atmosphere),
