How do I estimate the system resistance for this Fan application?
How do I estimate the system resistance for this Fan application?
(OP)
I'm planning on designing a centrifugal fan that will blow air for combustion of charcoal which is contained in a cylindrical drum but I need to know how to estimate the system resistance (the static pressure) and the flow rate.
Please, I'm new to fan design and I don't know how to get my fans flow rate and corresponding static pressure too. I don't know if there is a table where I can get further information to help in the design process. I've attached the complete design image of my machine for more understanding of what I'm trying to achieve.
Thanks.

Without knowing if you're blowing air over the top, from underneath, depth of charcoal etc I doubt you will be able to get a figure. Flowrate you can probably estimate based on over supply of air / oxygen, but a lot depends on what temperature you want to get to.
If you can find a small forge or smith where they heat horses shoes you might get an initial idea about flowrate and power.
search for it and you can find gems like this https://www.bladesmithsforum.com/index.php?/topic/...

control over the air supply seems to be required so you start low then increase as temperature required goes up.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

For more details about the machine:
The machine is design for frying Gari. As described earlier it has a cylindrical compartment for storing charcoal. The Gari mash is held by a pan separating the combustion chamber from the fring chamber where frying takes place with the help of a mechanical stirer.
The image belows shows the outline of the heating system in simple diagram
