[Dsg-ltcc] [New Logentry] S5 Flow Rate

[Maurizio Ungaro]

Hi Brian, George, 

a 0.065 l / minute flow is still 93 liters / day, which is about 1 1KG / day. George please correct me if I'm wrong.

The expected losses may be less than that. I'm worried about forcing flow and losing gas this way.

Thanks,
Mauri

S5 Flow Rate 


Lognumber 3523300 . Submitted by beng on Mon, 01/29/2018 - 13:28. Logbooks: 	HBLOG LTCC

The flow has been reduced another 0.1 slm from 0.4 slm to 0.3 slm. 

The plan is to reduce the flow every hour or so by 0.1 slm until we get to 0.1 slm (or the pressure starts to drop) and hold it there for the night. 

If 0.1 slm holds the flow will be set to 0.065 slm, which is slightly above the minimum flow value of 0.063 slm that the MFC can control.
