1. A mixer comprising:
a body;
a passage formed through the body;
an annular plenum circumscribing the passage and having an inner radius that is parallel with a sidewall of the passage and a frusto-conical cross section, the plenum in communication with a source of an injection chemical;
a port in the sidewall of the passage that is in communication with the plenum;
the passage having an end with an opening that is in communication with a primary fluid, the primary fluid being selectively combined with the injection chemical to create a combined fluid when a velocity of the primary fluid is at a threshold magnitude so that the combined fluid is mixed inside the mixer and becomes a mixed fluid having a designated homogeneity; and
a valve assembly in the passage that is moveable to a blocking configuration when the velocity is below the threshold magnitude and defines a barrier to flow of the primary fluid and injection chemical into the passage, and when the velocity is at least at the threshold magnitude the valve assembly being moveable to a flowing configuration and that permits a flow of the primary fluid and injection chemical into the passage.
