the actual indoor and outdoor air pressure difference is about and the air leakage rate

[Masoud Valinejad]

As an assignment my prof wants u to compare three kinds of wall. I am supposed to set "the actual indoor and outdoor air pressure difference is about 5 Pa, and you can assume the air leakage rate as 0.3 L/s.m2", but I don't know where I should set in software (WUFI pro).
Could you please help me?

Hi Masoud,
for that you have to insert a infiltration source.
