We are trying to design a new product which uses gas pressures
in various ways. We are a little foxed about partial pressures:
Imagine a small cylinder; 6in long + 1in in diameter.
The cylinder is made from steel.
The cylinder is divided into two equal compartments – A and B.
Each compartment holds pressurized gas at 80psi
In compartment A. the gas is air
In compartment B. the gas is Nitrogen
The wall that divides the cylinder is made from rubber.
The rubber is gas permeable.
Oxygen has a higher partial pressure than Nitrogen.
Oxygen is 21% of the gas in compartment A.
QUESTION:
Would that cause a change in the gas balance between the compartments over time?
For example: Would there be a transfer of gas from A to B?
Thanks Very Much.
