In the case of the motor it is the rotor and the stator and for the pump it is the impeller and the volute (or diffuser). Of course the friction produced by bearings and other mechanical components (seals, stuffing box, etc) also affect pump efficiency, but the impeller and volute have the greatest influence. Lets start our investigation of centrifugal pump efficiency with the impeller.
The only difference between sport coats and blazers is that blazers are always solid-colored, usually blue, black, camel or dark green, while sport coats encompass about everything else. Blazers are considered more basic and more formal than sport coats. Photo Credit Jupiterimages/Brand X Pictures/Getty Images.
Shaded sables are coats that are shaded throughout with three or more colors. This shading must be as uniform as possible with no patches of self color.
