In every situation where a heat exchanger is required, the combination of products and service fluids, application, temperature and other variables will be different. Understanding these properties ensures the correct heat exchanger is supplied. For example, high fouling materials may require a scraped-surface unit. Having adequate information will also ensure that the heat exchange process does ...
Solutions There are several ways to monitor viscosity including Kinematic Viscometers (u-tubes) per ASTM D445, Ametek Spectro Scientific’s MiniVisc 3000 per ASTM D8092, Visgages, Rheometers and Rotational Viscometers. Typically, ASTM D445 methods are run in a laboratory setting due to the glass capillary tubes and large constant temperature baths which are difficult to ...
The rheological study is done using an RS600 rheometer. Head losses and friction reducing are measured on three horizontal pipes (30, 50 and 80 mm). ...
Therefore, the ability to determine the rheology's dependence on shear is important when optimising systems with such liquids. However, rheometers capable of determining the viscosity are often expensive and so a cheaper alternative is constructed with this exact capability. Using the principle of rotating rheometers, a low-cost rheometer ...
This study evaluates the rheological properties of beneficiated mud using factorial design. Four-speed rheometer was used to determine the shear stress at different shear rates from which rheological properties were determined. ...
Effective rheological representative flow curves determined from speed/torque data proved comparable to off-line laboratory rheometer measured data. Modelling effective viscosity as a Power law function gave effective consistency coefficient Keff which correlated strongly with K from the rheometer (R2<SUP2< sup>=0.99). Effective flow behaviour index neff ...
The effect of solution chemistry on the behavior of kaolinite in three different situations was investigated: (1) the detachment of kaolinite from glass beads in a fluidized bed, (2) the erosion of kaolinite deposits in a laboratory flume and (3) the determination of the stress-strain rate relationship of concentrated suspensions in a rheometer. The experimental results from ...
