In this case the baffle helps increase the efficiency of the stove as more heat leaves the gas before it exits. The baffles prevent the rotational flow without affecting radial or longitudinal flow. The tank is provided with baffles which prevent swirling and vortex formation. Except in very large tanks, four(4) baffles are placed.
Depending on the type of phase and the viscosity of the bulk, the agitator may be called a mixer, kneader, dough mixer, amongst others. Agitators used in liquids can be placed on the top of the tank in a vertical position, horizontally on the side of the tank, or less commonly, on the bottom of the tank.
A slosh baffle is a device used to dampen the adverse effects of liquid slosh in a tank. Slosh baffles have been implemented in a variety of applications including tanker trucks , and liquid rockets , although any moving tank containing liquid may employ them.
Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n centiStokes. For gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 0.5 to 5 kg/m^3.
The settling rate and viscosity of the slurry are functions of the slurry density. The viscosity, in turn, controls the gas mass transfer and the leaching rate. Numbers of tanks - Agitated tank leach circuits are typically designed with no less than four tanks and preferably more to prevent short-circuiting of the slurry through the tanks.
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 ...
Internals include baffles that direct flow in a spiral pattern around the jacket, and agitating nozzles that cause high turbulence at the point where the fluid is introduced into the jacket. Half-Pipe Coil Jackets. Pipes are split lengthwise, usually with an included angle of 180 degrees (split evenly down the middle) or 120 degrees, then wound ...
Knowing the terminal velocity, the size and density of the sphere, and the density of the liquid, Stokes' law can be used to calculate the viscosity of the fluid. A series of steel ball bearings of different diameters are normally used in the classic experiment to improve the accuracy of the calculation.
