The RS is a radial turbine with 1/2 pipe blades. It is most commonly referred to as the Smith Turbine, after Prof. Smith. The original Smith Turbine did not use a full 1/2 pipe, but the commercialization of this impeller dictated this. The impeller was designed to disperse gases better than a Rushton Turbine (RT) and without the huge power drop. The RS was never patented and therefore is considered generic.

Turbulent Power Number Np=3.2, Flow Number Nq=0.61*

*The flow number is estimated by Post Mixing using the 1/3 power law and comparing it to the 6 bladed Rushton Turbine, RT6.
