Which would give higher accuracy in measuring volumetric airflow rate - a vane flow meter with a flow hood or an airflow chamber designed as per AMCA 210-99?

Is there a correction factor for sound pressure level if we want a value at 35°C instead of 25°C which is the actual environment it was measured? Say if we get 45dBA at 25°C, what should be the value at 35°C? Assume no change in air humidity.
I've been searching the Internet for typical electronic component values for materials data for heat transfer. So far I have been unsuccesful. I'm interested in discrete parts as well as ICs.
What could account for the difference in the system resistance curve for a device under test when the airflow direction is reversed say for a PSU from AC-inlet to connector vs connector to AC-inlet?
The air flows through the same components but expansion and contraction of air could differ with...
I have the system resistance data for an electronics enclosure (power supply) with Width, Height and Length. I need to approximate the system resistance curve for a similar enclosure but with reduced W and H and more or less same no. of components. Are there empirical equations out there that...
