Hello, I need help for my thesis project.

Lets say We have two tanks. Tank 1 is filled with methane and Tank 2 is empty

Tank 1:
V = 30L
T = 40C
P = 40psi

Tank 2:
V = 20L
T = 25C
P = 14.7psi

Two tanks are connected by a pipe with 2inch diameter (a valve in the middle is closed at first). Then the valve will open, so that Tank 1 will transfer methane to Tank 2. Then HOW MUCH TIME will both tanks have the SAME PRESSUE?

What formula shall I use? Need help. Thanks

Hello John, :welcome:

This may not be homework, but I think you may benefit from (at least mentally) using the template there to orser your thoughts and get effective assistance:

Homework Statement


well taken care of

Homework Equations


gas law, adiabatic expansion, pressure drop in a 2" pipe and/or in a contraction and an expansion

The Attempt at a Solution


your own ideas. Or you might look around for related threads in PF -- they definitely are here somewhere.

And -- not unimportant -- at what level do you do this ? For a PhD thesis the assistance might be somehaat more involved than for middle school... :smile:

Welcome to the PF. :smile:

As mentioned, you need to post this schoolwork problem in the Homework Help, Engineering forum and fill out the Template that you are provided there when starting a new schoolwork thread.
