G Factor (Velocity Gradient)
The G (or GT) factor, indicative of power per unit volume, was developed in the 1940s as a means of determining dynamic mixer performance in stirred tanks. More recently, attempts have been made to use G factor to describe static mixer performance, especially in water treatment dosing applications. However, G factor does not consider how effectively a particular mixer design converts power to mixture quality, neither does it consider how effective the injection method is. For these reasons, Statiflo has not adopted G factor as a useful tool in static mixer design.
