Dear all, please, someone has any idea about my issue (attached figure)?
I have a fan with a known flow rate and i need to put a 'hole' next to the fan in order to insert fresh air.
In this hole, ill install a damper and my problem is: how much air (atmosferic) will go inside the piping related to % of open damper?
Example: if i made my damper 100% open, how much air will go?
I need to solve this problem because i will need to increase/modify my main fan speed (in order to increase the flow too)
There is a equation solve for this?
Thank you all!
