The following is the data for an application: Fluid composition: Hydrocarbon/Acid/Water/0.5% suspended solid Solid concentration %w/w: 0.5 Motor: 24.79 hp Speed: 68 rpm Single impeller downflow turbine type, with a steady bearing about 800 mm above the impeller. Can you please give the service factor that needs to be used while computing the hydraulic unbalanced load?
Have an insight or suggestion?

Re: Service factor for an unbalanced hydraulic load19 September 2006 at 1:29pmIf the impeller is always completely submerged (more than 1/2 the impeller diameter below the liquid surface), a hydraulic service factor of 1.0 is adequate. If the impeller is operated at the liquid surface (while filling or emptying the tank) the hydraulic service factor should be 3.0.
