Abstract: In this study, the dilution characteristics of tee diffusers have been studied experimentally for a wide range of ambient current conditions. Experimental results for tee diffusers show that, when m r < 1, dilution decreases with mr, whereas, when m r > 1, it increases back as mr increases further, and asymptotically approaches stagnant water dilution for very large values of mr. Existing predictive equations provides a reasonable fit to the data in the region of weak to moderately strong current, however, those equations give a poor fit in the region of a significantly strong current. A new equation suggested in this study provides a better fit to the data.
