B Trying to understand wind forces on a door

[Bendimac16]

So far, rn since i am making a theory, though im coming in a problem, if por example if im talking about of human force against wind, then who would be stronger, considering which impacts more? Idk it just looks a dumb question just to see how much force i need to do if the wind is strong to win it a close the door compared to normal

It's not a very well thought out question. It depends on how fast the wind is blowing. I mild breeze blowing at 2 o4 3 kilometers/hour doesn't exert much force in comparison to wind that is blowing at, say, 120 km/hr.

This is not the place to post personal theories.

So, for instance, you are standing at your front door. The door is open and the wind is blowing into your house through the open door. The door opens inward. You are standing in the house and want to swing the door closed. You slowly push the door closed against the force of the wind. You want to know how much force is required to accomplish this.

Does this match what you have in mind?

The first thing that I would consider is the "stagnation pressure" of the wind (Google it). Bernoulli came up with a formula for that.

The next thing that I would consider is where to push on the door. If the door is hinged on one side, where should one push to get maximum leverage?

Note that how hard it is to close a door in the scenario above depends on wind speed, direction, and how "tight" or "leaky" the building is. If there's no leakage there's no airflow though the door and no force required.
