The Standard Tank Configuration

The standard tank configuration is a useful reference standard for mixing process design. It provides adequate mixing for most processing requirements found in industry. However, it should be stressed that the Standard Tank Configuration is an arbitrary standard which in some circumstances is not the best configuration to use. For special processing conditions, such as mixing liquids with a high solids content, a high viscosity or a shear sensitive character, this configuration may be impractical.

The Standard Tank Configuration has the following geometrical relationships:

THE AGITATOR	A standard 6 blade flat blade turbine impeller
IMPELLER DIAMETER	Di	= 1/3 tank diameter Dt
IMPELLER HEIGHT FROM TANK BOTTOM	Hi	= 1.0 impeller diameter Di
IMPELLER BLADE WIDTH	q	= 1/5 impeller diameter Di
IMPELLER BLADE LENGTH	r	= 1/4 impeller diameter Di
LIQUID HEIGHT	Ht	= 1.0 tank diameter Dt
BAFFLE NUMBER	Quantity	= 4, vertically mounted at the tank wall and extending from the tank bottom to above the liquid surface
BAFFLE WIDTH	Wb	= 1/10 tank diameter Dt
