thanks this is very useful, so we know we are not in trouble in 2 month from now. SO if we now also find out the PHENIX NOVEC is still good, we are good to go.

Thanks elke

Hi Elke, all,

As we discussed in today's FST meeting, Yu and I checked the NOVEC 7200 information.

We have 3 new barrels of NOVEC left. 

Each barrel contains 15kg/33lb of NOVEC  with 12.3 L in volume (listed on the NOVEC website), even though the destiny of NOVEC is 1420 kg/m^3 which translates to 10.5 L per barrel.

The cooking rack capacity is 7 Gal, which is about 26.5 L in volume. Therefore, one barrel could fill about 40~46% of total capacity from the calculation.

We also refilled the tank with 2 L of NOVEC (with the help of Greg) and the tank level changed from 43% to 54%. The fill rate is about 5.5% per litter. Therefore, one barrel of NOVEC should fill about 55-65% from the test.

The leak rate is about 5% per 9 days. 

If we assume the leak rate is 5% per week (maximum leak rate) and each barrel could fill 40% of the tank (minimum fill rate), then each barrel could last for 8 weeks at least.

3 barrels should be sufficient for about 24 weeks of use.

Hope this helps.

Best,

Xu
