You don’t u defeat d fluid dynamics well do you. fluid (or air) traveling through a smaller space speeds up. It likely increases the distance. the point is the virus and drillers are it stopped by the mask they are sprayed into the environment.

Well, if you narrow the opening on a hose, it does increase the distance the water goes. The situation is probably different with air, though, and with a good bit of room for the air to spread out in different directions. Before the days of home air-conditioning, I’ve sat in rooms with a stationary fan. I much preferred being directly in line with the flow of air to being behind some furniture that would deflect some of it.

This should be easy to test, though. Just cough with your mouth uncovered and feel the pressure when it hits your hand held a couple of feet away. Then try it with the mouth covered (I’d already done that testing in front and didn’t feel anything.) Move your hand to various positions to the side and the same distance away, and see if you can find a point where you can feel the air as strongly or, as you claim, even more strongly than uncovered in front.

I just tried it, and couldn’t find a place where the air is felt as strongly as uncovered. In fact, at about two and half feet, I didn’t feel anything.

I said, “I much preferred being directly in line with the flow of air [from the fan] to being behind some furniture that would deflect some of it.” I also don’t recall feeling the air stronger to the side of a barrier. If that were true, when alone in a room, I would have put a barrier in front and sat to the side.

Actually I just realized that I’m in a situation in which I can test this theory. I sleep and use my computer in the same room, but have my window air-conditioner in an adjacent room, at a right angle to this one. (I don’t want it in the same room because if it’s nearby, the air-conditioner cutting on and off wakes me.)

A few feet from the door of the other room I have a cabinet slanted toward this room that partially deflects the cooled air being blown by the fan from the air-conditioner. Standing in front of the cabinet, I can feel the air well, standing to the side toward my room, I do feel the air, but it’s barely perceptible.
