[NSRCA-discussion] Cooling/spinners

Nat,

You are correct.  Power consumption for any centrifugal machine is function of the flow rate at the third power "called fan laws".  Adding a properly design fan in the spinner would increase the power consumption.

As Matt mentioned, the only way to use the spinner as an effective air mover is as a cetrifugal blower. This would call for an open nose, and the need for  properly shaped vanes (as a third part ?).

As I recall, power consumption ( volume ? ) is a function of the cube of the RPM. I need help here, its only been 60 years.                                     Nat
