Can I control the airflow in my apartment by opening one window (of two) more than another?

Question

I have a 12th story apartment, and I smoke near the window. Obviously opening 2 windows creates air flow, but can I control the direction (in or out) of the air flow by opening one window more than another?

Answer 1

Nope. Wind (or "air flow") is caused by a difference in pressure between one area and another. Air will flow from a high pressure region to a low pressure region. (That's why the weatherman is always talking about high and low pressure.) Opening your windows varying amounts won't have any impact on the air pressure outside your window, so the air will flow in or out regardless of how far the window is opened.



What you _will_ affect is the flow rate. If you open the window wide there will be less of a breeze than if it's opened just a little bit. (This is the same principle as using a nozzle on a hose.) Of course, the difference won't be noticeable unless there's a _huge_ pressure difference between the two sides of your building (i.e. it's really, really windy outside).

Answer 2

There is crossing of air from opposite windows.If one window is partially open(inlet) and other full open(exit),there is less air comes in room and that air warms and lift upwards and same less amount air go outside rather u have fully open window.

Answer 3

one window will be no air flow at all.

Answer 4

No
