Diameter of tank D t or the diameter of impeller D a are the suitable choices for the base measurement.

Types of Washing Machine Agitators Hunker ,Straight vane agitators are common on most top loading washing machines. These agitators consist of a single piece of molded plastic fit over the agitator hub. Vanes project from the side of the agitator. The entire agitator spins inside the washing machine tub providing the cleaning action for the clothes inside.

AGITATOR meaning in the Cambridge English Dictionary ,agitator definition: 1. someone who tries to make people take part in protests and political activities especially ones…. Learn more.

How To Choose The Right Agitator Sepro Mixing ,Once the process aspects of the mixer design are finalized we’ll need to optimize a final design that uses power efficiently. This could mean altering the D/T impeller to Tank Ø ratio to produce the same process result at reduced power. The price to pay will be torque which could require larger gearboxes using lower power.

Problems in Stock Agitation - James Brinkley ,Agitators with overhung shafts run up against the problem of fluid forces. Generally agitators want to produce axial flow or flow in line with the shaft axis since this provides the most mixing. But no propeller is perfect at this so radial forces are produced. Inflows impinge on or close structures interfere with flow.

Process Engineering Don& 39;t get mixed up by scale-up . ,For such a scenario both the turbine diameter D and rotational speed N must change as the volume increases. To keep tip speed constant we can use the relationship: vTIP ∝ ND. Then per Eq. 1 for constant tip speed: N 2 D 2 = N 1 D 1. For torque per volume the following relationship based on turbulent conditions applies: t/V ∝ N 2 D 5 /V
