[Dsg-rich] decrease Nitrogen flow to see how RICH humidity is affected

[Tyler Lemon]

Hello Marco Contalbrigo, 

Today, it would be good to do a test overnight to see how RICH's internal humidity is maintained if its nitrogen flow is decreased. 

RICH is now in a steady state with its internal humidity at or below ~3%. We could lower the nitrogen flow from ~35 L/min to ~25 L/min to see how, if at all, the internal humidity changes overnight. 

If we are able to maintain an acceptable humidity with a lower flow, it would lessen the chances that we will run out of nitrogen over the shutdown. 

Best regards, 
Tyler
