Some products that may require laminar mixing in a high viscosity mixer include putties, chewing gum, and soaps. [1] The end product usually starts at several hundred thousand centipoise and can reach as high as several million centipoise. Typical mixers used for this purpose are of the Double Arm, Double Planetary or Planetary Disperser design.
One such complicating feature is the relation between the viscosity model for a pure fluid and the model for a fluid mixture which is called mixing rules. When scientists and engineers use new arguments or theories to develop a new viscosity model, instead of improving the reigning model, it may lead to the first model in a new class of models.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
The energy needed for mixing comes from a loss in pressure as fluids flow through the static mixer. [2] One design of static mixer is the plate-type mixer and another common device type consists of mixer elements contained in a cylindrical (tube) or squared housing. Mixer size can vary from about 6 mm to 6 meters diameter.
Anyone employing an incubator shaker (thermal shaker) to grow yeast or bacteria in the laboratory needs to beware that under the usual conditions encountered in the lab, the rate at which oxygen diffuses from the gaseous phase into the shaken liquid phase is too slow to keep up with the rate at which the oxygen is consumed by, for example, E ...
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
This template produces a NFPA 704 safety square with optionally four hazard codes. It is designed to be used in a table. It is designed to be used in a table. Primary use is through {{ Chembox }} , the {{ NFPA 704 }} box and {{ OrganicBox complete }} (chemical data pages).
A vortex mixer, or vortexer, is a simple device used commonly in laboratories to mix small vials of liquid. It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off-center.
