How to Calculate Volumetric Flow Rate from Pressure Change in a Chamber?

[wadswwc]

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

Hi Trae, welcome to the board. Fluid flow through pipes is typically analyzed using the Darcy Weisbach equation. There's a thread https://www.physicsforums.com/showthread.php?t=179830" that provides reference material and some discussion on it.
