iam confused so much about some concepts of turbomachinery.(adsbygoogle = window.adsbygoogle || []).push({});

according to the classification of rotodynamics devices there are 3 types radial flow,axial flow and mixed flow and axial flow gives higher flow rate compared to radial flow and lower head.

so my question is what is meant that axial flow gives higher flow rate and lower head ?

cant we convert kinetic energy(flow rate) to pressure (head) and vise verse so the point is how much the power input to the device so we can convert this power to to flow rate or head regardless the type of rotodynamic(axial or radial) i.e the diection of flow

another question does the design of impeller or propeller has to do something about that?

finally i hope if you can get m,e a source (website or books)that clearify this point and clarify the the design of impellers and animations .
