Hi All, I must calculate the torque and for an agitator motor. An anchor type agitator/scraper, removing crust off the edge of a tank. My instinct is the max or startup torque will be = (Moment of Inertia) x (Angular Acceleration) + (Drag force of the submerged impeller)* Max radius + (Frictional forces on the edge of the tank)* Max Radius

Estimation of Agitator Flow Shear Rate Jie Wu, Lachlan J. Graham, and Nabil Noui Mehidi ... Shear rate of the flow in a mixing tank is an important ... it is a common practice to calculate the average shear rate at the flow exit plane of impellers, within the impeller diameter periphery. It is therefore proposed here that the shear rate as

The following report is a summary of work conducted to evaluate the ability of existing correlative techniques and alternative methods to accurately estimate impeller speed and power requirements for mechanical mixers proposed for use in a mixing and sampling facility (MSF). The proposed facility ...
To design the agitators, there is a need to calculate the =, =, =,-----(1) electric power of the motor according to the tank size and liquid type. Where 5. When calculating the electric power of a motor, we are Da Impeller diameter, urged suppose that the tank is cylindrical.
Number of agitators = (Maximum liquid height x specific gravity) / Diameter of tank. Gap between two Agitators = Liquid height / (Number of impellers - 0.5). Basic Design Equations for a Vertical Vessel and Agitator: Vessel Volume = (pi x vessel dia x vessel dia x vessel length) / 4.0
However, at the end of the batch, CO 2 evolution almost stops, so the pump or agitator must blend the tank and keep solids in suspension to the extent possible. The tank size is 198" (5.03m) diameter, shallow bottom, with a working volume of 40,800 gallons (154 m 3). Tank contents have an average specific gravity of 1.0. Pump Description
59.85 time 100 equals 5,985 cu. ft. (total volume 24 hour agitation). Therefore, 5,985 times 2 equals 11,970 cu. ft. (Total volume 48 hours agitation). We find that 15′ x 4.5″ x 16′ and 1″ Bolted Steel Tank has an available capacity of 2,860 cu. ft.; therefore, four of these will handle the job. Or we find that four 15′ x 16′ Welded ...
Step-1: Power calculations and selection of motor For required power calculations, selection of the type of impeller is very important to achieve required agitation power. Selection of impeller is done based on application and type of flow. Flat paddle, turbine, anchor type, …
The mixer selection program allows you to calculate flow rates and power draw of mixing impellers, see what the agitator will provide for tip speed and tank turnovers per minute, and give you some rough estimates on tank mixer sizings.
Non-cylindrical mixing tanks are usually either rectangular, or horizontal tanks, and as previously mentioned these tanks usually do not require baffles unless the required level of agitation is high. These tanks are asymmetrical with respect to the mixer shaft and as a result are self-baffling for applications where the applied mixer power ...

Four baffles are installed around each agitator at 90-spacing along lines connecting the agitator shaft center with the four corners of a pit (Figure 10.11). For a long rectangular pit with two or more agitators, the tank is divided into imaginary square compartments and a baffle is pointed at each corner (either actual or imaginary).
Type of Agitator: Generally it is mounted vertically at the top of the tank. This is the normal practice for mounting an agitator in small and medium size tanks. It is also mounted horizontally from side of a tank, called side entering agitator, for very large diameter storage tanks. Pattern of Circulation: Axial or Radial. When a vessel is ...
The Agitator system is compatible with all measurements while drilling (MWD) systems with proper pre-job planning. Section 3c. provides instruction on proper tool setup, allowing operators to ensure that the Agitator and MWD systems do not interfere with one another. Each MWD company has specific setup guidelines to follow when

Location of agitator in the equipment: Generally agitator is centrally located for better flow pattern. Agitator is located off-center if some part of vessel is occupied by internal coil or some other internal. Shape and size of tank: Vertical cylindrical vessel is the best type for installing an agitator. However, agitator is also installed in ...
