    What do you want to test it for, head, flow, efficiency what does it blow and what does it do with the fluid that it blows?

    With a question that simple, here is a simple answer:

    - You connect it to a motor of known power output.

    -You measure the pressure and temperature at inlet and outlet, and the mass flow rate.

    - From those numbers, you calculate the actual power done on the fluid.

    - Divide the actual power done on the fluid by the known shaft power to obtain the efficiency of the unit.

    - Repeat for different rpm, throughout the rpm range.

    A text book on Applied Fluid Mechanics or similar will have a section on blowers.

    Basic info can be obtain on this http://www.turbobygarrett.com/turbobygarrett/tech_center/turbo_tech103.html?" [Broken]. It's about turbos, but the compressor of a turbo is a centrifugal compressor which is connected to a turbine instead of the crankshaft. So what applies to one, applies to the other.

    For more detailed info on their designs, you need a book about turbomachinery similar to this http://books.google.ca/books?id=s4Q...resnum=3&ved=0CDgQ6AEwAg#v=onepage&q&f=false".

    There is a standard for blower testing: Performance Test Code (PTC) 10. It provides a standard method to measure a blower head / flow curve.
