[Amps] Blowers for metal-ceramic tubes

[Ian White GM3SEK <gm3sek@ifwtech.co.uk>]

I have posted an Excel spreadsheet that will estimate the performance of 
a centrifugal blower from the wheel diameter, width and rpm.

This can be compared with the requirements for any particular tube, 
using the manufacturer's data for the required volume flow rate and 
pressure.

The spreadsheet uses the method published by G8WRB, and is on the 
website below. (Try to live with the mixed units, Carl  :-)
