Secondarily, should the fan be outside or inside the window?
Asking for a friend. (Me, help. I can’t remember physics, it’s too goddamn hot)
Edit: I’ve opened all the windows and set up a fan a short distance from the window pointing out and it’s reduced the temperature to near-tolerable levels. Unfortunately, venting through the attic was a no-go but moving things aside might make it an option next time. Thank you all, I appreciate the help!
I think you get the benefit of the airflow pulling in air along its edge to push out with it.
Like pushing a bunch of water with a broom removes not only the water in front of the broom but also more water due to surface tension and inertia
It’s called the venturi effect.
