  1. The volume of an outside gHe tank: 1600 cubic feet (V = 45306.95 L)
  2. 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
    1. P_atm = 14.7 psia
    2. C_gL = 750 — 1 L of LHe = 750 L of gHe @ 300 K, 1 atm
    3. P_gHe ~ 100 psig (not psia)
    4. L_LHe = V * (P_gHe + P_ATM) / P_ATM / C_gL
    5. R_gL = L_LHe / (P_gHe + P_atm) = V / P_ATM / C_gL = 4.1 L/psi
  3.  The pressure increase in the gHe tank per tube (in the tube trailer) is 10psi (i.e. 10 psi difference per tube)
  4. 100 slm rate on Magnet FC is equivalent to ~ 192 LHe liters per day (i.e. assuming both LQ A and B are running)
  5. QT recommendation to keep system minimally pressurized: ~20 psi
  6. 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).
  7. Putting a 2200 psi gas bottle into the system will produce 8 liquid liters per bottle.
