- The volume of an outside gHe tank: 1600 cubic feet (V = 45306.95 L)
- 1 psi of gHe at 300 K in the outside gHe tank = 4.1 L of LHe — R_gL = 4.1 L/psi at 300 K
- P_atm = 14.7 psia
- C_gL = 750 — 1 L of LHe = 750 L of gHe at 300 K, 1 atm
- R_gL = V / P_atm / C_gL = 4.1 L/psi
- The pressure increase in the gHe tank per tube (in the tube trailer) is 10psi (i.e. 10 psi difference per tube)
- 100 slm rate on Magnet FC is equivalent to ~ 192 LHe liters per day (i.e. assuming both LQ A and B are running)
- QT recommendation to keep system minimally pressurized: ~20 psi
- Running from 40 psi down to 20 psi would produce about 80 liquid litters and we should be able to do that in about 10 hours (assuming both LQ A and B are running).
- Putting a 2200 psi gas bottle into the system will produce 8 liquid liters per bottle.
