Solved Example 3: Two water taps can together fill a tank in $$9\frac{3}{8}$$ hours. The tap with the larger opening takes 10 hours less than the tap with the smaller opening to fill the tank (separately). What is the time in which the larger tap can fill the tank? Solution: Let V be the volume of the tank

• ### how to fix agitator mixer problems in a gold leach circuit

The existing agitator impellers were too small and did not provide a sufficient impeller/tank diameter ratio. This design problem caused solids to build up around the walls and bottom of the leach tank, reducing the effective size of the tank and lowering the actual leaching time for the active slurry
