Question: When using a pumping loop to mix two miscible fluids in a tank, when can the content be consider well mixed?
Keywords: mix,tank,pump,well,mixed
Answer: A rule of thumb is to turn the tank over three (3) times and then sample the tank for mixture properties. By "turn the tank over" we mean to force the entire volume of the tank through the pump at least three times. More turnover may be necessary, but three times is a good starting point.
