static pressure

If it's an axial flow fan,it shouldn't have a duct attached to it these type fans don't operate very efficiently against static pressure, if it,s a squrrel type fan with no discharge duct then you have no static pressure and if you have attached duct(resistance) then I suggest you read this:
You don't.
Use a reliable and trustworthy fan manufacturer and that will tell you what airflow you are getting.
BUT, if you want to have some idea of airflow, use a hood.
The hood however will interfere with the readings and give you a lower airflow than it really is capable of

Use a manometer and place one tube on each side of the wall.

If you want to calculate it, you will need to evaluate the path the replacement air takes getting into the room. Then make a curve of dp verses air flow into the room. Overlay the fan curve and where the two lines intersect will be the calculated static pressure in the room.
