I'm trying to calculate the dilution factor of two gasses. I have a gas that is mixed with zero air using a timed valving scheme. Both the gas and zero air use a common flow rate(200ml/min). This is plumbed in such a way that the output of the previously described gas is ran into a three-way inlet with zero air at a variable flow rate(X). My questions is how do I calculate the final dilution factor if I know the stage one flow rates, the initial dilution factor, and the second stage zero air flow rate?
Thanks to anyone that can help me!
