A Coaxial Cylinder Type Rotational Viscometer- Design and Optimization
The history of viscosity measurements is outspread and is believed to date back to when people began measuring the viscosities of engine oils with the advent of the automobile industry [1]. A rotational viscometer is one which can be used to measure viscosity at different temperature. In this treatise, a coaxial cylinder type rotational viscometer (CCTRV) has been designed, constructed and comp...
متن کاملProcedure to Evaluate the Shear Rate Profile and the Apparent Viscosity of Non-newtonian Fluids in the Falling Cylinder Viscometer
−− The falling cylinder viscometer (FCV) is a reliable instrument to quantify the viscosity of Newtonian fluids. Nevertheless, when nonNewtonian fluids are tested in this device, difficulties appear to determine the apparent viscosity. Thus, conventional rheometric calculations cannot be applied directly to experimental data provided by the FCV in order to obtain the apparent viscosity function...
متن کاملThe Micromagnetoflowcell - A Microfluidic Viscometer
An experimental micromagnetoflowcell viscometer was fabricated to enable viscosity measurements for microscopic quantities of liquid. The device uses measurement of the terminal velocity of superparamagnetic microparticles to determine the fluid properties. Motion of these particles is controlled by the magnetic field generated from microscopic electromagnetic loops. Analytical modelling has be...
متن کاملA New Viscometer
A viscometer is described, particularly adapted to the measurement of colloidal solutions and physiological liquids (serum, blood), which, although doing away with the capillary tube (which is difficult to handle and to clean), requires less than 1 cc. of liquid. The readings are rapid, from 30 seconds to 1 minute. The temperature is easily controlled and varied. The range is considerable and m...
متن کاملMinute Volume Viscometer
In the field of pharmaceutical research, injectable treatment therapy is currently one of the most highly examined methods of drug delivery. The continuation of this research is highly dependent on knowledge of fluid properties, specifically loss and storage modulus. Most drugs in the developmental stages of this method are extremely expensive and limited in quantity. Currently, devices that me...
