How Does Wind Speed Affect Indoor and Outdoor Air Pressure Differences?

[JRose]

Outside wind blows at 30.2 m/s. Assuming the inside air is stagnant, what is is the pressure difference between the inside and outside environments? Answer in Pa.
I know that pressure is F/A or Rho(g)(h)...but all I have is velocity! Help?

Thank you kindly!

(This has got nothing to do with rho*gh.)

The wind hits the wall and transfers momentum to it, resulting in pressure.

What is pressure? Think about the relationship about force and change in momentum. Tell us your ideas first.

 

[JRose]

Pressure-force exerted on an area. But force relies on an acceleration, where here the wind speed is constant.

What principles rely solely on velocity?

Do you know what the impulse of a force is? And any thing else related with it?

 

[JRose]

Ooh. Only vaguely. Impulse has to do with energy transferred in a certain amount of time? (If I'm wrong, my apologies. This was months ago.)

 

[JRose]

Sorry, change in force over a period of time?

 

[Shooting Star]

For a constant force, impulse = force*time. It's also equal to somthing else. If you read up just a bit, then the answer will make sense. Pl do that and come back here.
