Total units of ammonia per tank, 5,652. Average units of ammonia per tank, 16.73. 8 per cent of moisture, dry basis.

This production at $1.66 per unit would be worth $27.77 per ton, or the yearly production would bring $24,396.32.

Figuring the production of tankage to be 66,000 pounds per week and that with this could be mixed through the dryer 600 pounds or 107.3 gallons of stick, 25° Beaume with each ton of dry tankage—then 33 × 600 pounds, or 19,800 pounds, would be the limit of production from the tank water.

The regular tankage runs on an average of 10 per cent ammonia and 16.4 bone phosphate, and as shown above the production from the tank water with 8 per cent moisture would run 16.73 per cent ammonia. The product would therefore consist of the following:

Value per ton $19.93, or for the yearly production, $44,459.84.

Should there be added worthless material sufficient to reduce the percentage of ammonia to 10, the following formula would apply:
