The head or pressure of a centrifugal fan can be expressed as.
Irrespective of design criteria an impeller s aspect ratio should ensure that its airflow is not compromised.
With particular regard to centrifugal fans.
Depending on the number of blades designed for each fan the total impeller grid was approximately 3 to 4 million cells.
