Homework Help Overview

The discussion revolves around understanding how wind speed affects pressure differences between indoor and outdoor environments, specifically in the context of a scenario where outside wind is blowing at 30.2 m/s and the inside air is considered stagnant.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between wind speed and pressure, questioning the definitions and principles of pressure and force. They discuss the implications of momentum transfer and the role of impulse in understanding the problem.

Discussion Status

The discussion is ongoing, with participants prompting each other to clarify concepts related to pressure and impulse. Some guidance has been offered regarding the relationship between force, momentum, and pressure, but no consensus or resolution has been reached yet.

Contextual Notes

Participants are grappling with the definitions and relationships between various physical concepts, and there is a noted absence of certain information, such as the specific context of the indoor environment's conditions.

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.
 
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?
 
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.)
 
Sorry, change in force over a period of time?
 
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.
