Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

Here's a simple problem...

My friend from engineering school posed this seemingly simple situation and its been bothering me that I can't figure it out.

With a known airflow rate (cubic-m per hour, or cubic-feet per min) into a room, assuming no leakage. What would be the average pressure felt at a standard doorway (say A x B metres or feet in dimensions)?

Which formula would you use to arrive at real-world results? Any other parameters to be considered in coming up with the answer?

The desired result would be in Pa (pascals) but any input you have would be most appreciated!

:)
