If the same volume of gas were in 2 different types of cylinders and there is a valve at the top with an equal diameter. The first with a large radius and small length, the second with a smaller radius and greater length.
Say the valve is then opened. Would the flow out of the containers be identical even though the surface area is not?
I'm wondering if the expanding gas colliding against the container versus each other make a difference. Equations would be great!
If the pressure in the tank is significantly greater that the pressure outside the tank and the area of the valve opening area is small compared to the cross sectional area of the tank the release rate will be dependant on the choked flow and they'll both be the same.
