Click For Summary
To test a centrifugal blower, connect it to a motor with a known power output and measure the pressure, temperature, and mass flow rate at both the inlet and outlet. Calculate the actual power delivered to the fluid and determine the efficiency by dividing this power by the known shaft power, repeating the process across different RPMs. For additional information on blowers, resources include textbooks on Applied Fluid Mechanics and turbomachinery, as well as online materials related to turbochargers. The Performance Test Code (PTC) 10 outlines standardized methods for measuring blower performance. Understanding these testing methods is essential for optimizing centrifugal blower efficiency.

centrifugal blower ?

how can i test a centrifugal blower ?
 
Engineering news on Phys.org


eeeeeeeeeeeeeh no answers ?
 


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.
 


thanx for your very simple answer :D
can u tell me i need more information about blowers where can i get it ?

A textbook 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?" . 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.
