AI Thread Summary
To calculate the volumetric flow rate from pressure change in a chamber, the Darcy-Weisbach equation is commonly used for fluid flow analysis. The scenario involves a pressure drop from 11 psi to 6 psi over 0.25 seconds, with air as the fluid at a temperature of 277K and a chamber volume of 0.01 m³. Additional information needed includes the specific characteristics of the flow, such as the pipe diameter and length, as well as the viscosity of the air. Understanding these parameters will help in applying the appropriate equations to determine the flow rate. Accurate calculations will depend on these variables and the correct application of fluid dynamics principles.

Hey so I am trying to calculate the following scenario.

I have a chamber that must change in pressure at a certain amount of time. I need to find the volumetric flow rate coming out of the chamber.

Here is the info I have
P0=11psi, P1 = 6psi
Change in time = .25s
Fluid = air
Temperature = 277K
Volume of chamber = .01m3

I don't need an answer I just need direction, what equations to use, what additional info I need.

Any help is much appreciated.
Thanks,
Trae

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
