I have an instrument that is technically a humidity controlled chamber. It measures how much moisture is picked up by the sample through a microbalance(Zone 1). Nitrogen gas flows from zone 3 and split into 2 chambers (by a union Tee ) in Zone 2. Finally the gas is vented in Zone 1, each chamber with its own exhaust vent (tubings that vent to the back).
The Problem is that the flow is uneven. or let me rephrase, the flow is even as long as the resistance against the flow is equal for both chamber. with the slightest change in resistance at one of the vents, the flow is completely diverted to the other chamber. This happens if one of the vent tubings got slightly bent, one is slightly longer than the other, etc.. It is ridiculous sometimes
My question is: if I joined the exhaust tubings together at the end (by a Y-connection), would that equalize the pressures and gas flow in the chambers? I'm no engineer but I can't think of a better place to ask
