[Dsg-rich] Humidity monitoring

[Pablo Campero]

Hello, 

Some of the humidity sensors readouts present even lower humidity values than yesterday, nitrogen flow is stable at 12.77 [slm]. 

Best Regards, 
Pablo

thanks pablo, 
hate to say things are going well, 
because that means we don't know what the hell is going on! 
(american double-speak) 

maybe maxwell's demon (physics double-speak for improbable events) read my earlier e-mail and like the grinch who stole xmas, stole my xmas puzzle. 

anyways, heard my wife whisper to my daughter, who asked who is pablo, "he's dad's blue eyed boy". 
now that's real tough to decipher. 
wish a goodnight 
amrit

Hello Amrit, 

Nitrogen flow was stable since yesterday 12/25/17, flow has not dropped today (~12.77 slm). Good news is that all humidity values dropped a little bit (~0.2 %), see attached screenshot. 

Best Regards, 
Pablo

hi pablo, 
thanks for monitoring the RICH. 
trust you had a good xmas. 
as you see the the flow rate has dropped a little, but we are still on track. 

xmas puzzle. 
we have 4 dewars in parallel. 
each dewar is essentially full. 
each has its pressure limited to 35 psig. 
exit pressure is 15 psig 
so why is the flowrate dropping for every 4% /day reduction of liquid N2? 
amrit
