Table 6 - 20 Preparation of Sodium Bromide Based Solutions Using 10.0
lbm/gal NaCl Solution and 12.4 lb/gal NaBr Solution
* Data being reconfirmed
Example:
To prepare 10 bbl of 11.0 lb m /gal NaBr:
10 × 0.583 = 5.8 bbl 10.0 lb m /gal NaCl
10 × 0.417 = 4.2 bbl 12.4 lb m /gal NaBr
Add 5.8 bbl of 10.0 lb m /gal NaCl to 4.2 bbl 12.4 lb m /gal NaBr.
