Question about airflow

[Greenlizard0]

Is there like a calculator or something that can e.g. calculate e.g. the quantity of air flow through your case depending on input variables such as e.g. no. of fans, speed (RPM) etc?

Hope that isn't too vague, I'm very hungover

I doubt it because all fan blades have different surface area, different size, angle, curvature and number of blades.
