keyword=Helium bags for BigBite
I removed the input tube from the top of the second bag and put the plug
in place. The bottom connection already had its plug in place. I found I
had mislabled the 1/2" polyflo vent tube at the end in the Gas Shed. The
correct tube had been capped off. I removed the cap and put the correct
label on it. I changed helium cylinders, the first one had run out. I
filled the first balloon by directly connecting it to the regulator. I
put more mineral oil in the overpressure bubbler and reconnected the
balloon input. The exhaust line from the bottom of the first balloon is
now connected to the 1/2" polyflo vent out of the hall. I set the flow
rate to about 0.3ft**3/hr.
