This book covers the essentials of fluid mechanics and explains how to apply fundamental principles to achieve optimum time and capacity efficiency with a minimum of waste. Individual chapters are devoted to the mixing tank, power consumption in turbulent flow, power consumption in viscous creeping flow, mixing in turbulent agitated tanks, and laminar mixing and gas dispersion in agitated tanks. measurements inside stirred tanks of varying size, over a range of operating speeds and thus covering a range of Reynolds number1-14. The focus has mostly been on the scaling of time- or phase-averaged mean quantities, primarily the mean velocity, and to6,9.

Design equations have been developed to estimate liquid velocities and mixing times in air agitated tanks. Determination of the gas rate necessary for adequate agitation in a given geometry is possible with this information. Air agitation offers benefits of increased

has focused on mixing performance in terms of the mixing time for different tank, impeller, and injection configurations. Kram-ers et al. (1953) were among the first to report on mixing time in a propeller agitated tank as a function of the baffle position and impeller

2009/6/4Blend time generally is determined by adding a small quantity of liquid to an agitated batch of similar property liquid. Laboratory tests most often add a liquid that results in a color change, from some hue to clear, and conduct tests in transparent tanks — allowing observation of the final color change indicating a degree of complete blending, no matter the location in the tank.

In this study, the conventional evaluation of mixing was done through experiments with different concave Impellers in a fully agitated baffled tank with two impellers. The electrical conductivity method was taken for the measurement of mixing time. 0.05 weight percent of CMC solution, which indicates pseudo plastic behavior of the fluid, was used as continuous phase and air as the dispersed phase.

Plastic mixing vessels offer advantages over steel mixing tanks including cost, weight, rapid fabrication time compared to stainless steel and the ability to see liquid level. Metal tanks are more resistant to cracking and temperature effects but they require polishing of the base metal and welds and so the cost to manufacture is typically much higher than plastic tanks.

Submerged recirculating jet mixing systems are an efficient and economical method of agitating large tanks with a high hydraulic residence time. Much work has been carried out in developing design correlations to aid the predictions of the mixing time in such systems, with the first such correlation being developed nearly 70 years ago.
