The viscosity versus shear rate behavior for a range of temperature for low density polyethylene melts at a range of temperatures. Original data source, J. Meissner,Kunststoffe, 61, 576–582, 1971. The data is replotted fromDynamics of Polymeric Liquids I: Fluid Mechanicsby Birdet al.6. Full...
Viscosity versus shear rate profiles for emulsions with (a) no gelation of the internal phase, (b) gelation of the internal phase.Kanyas, SelinAydın, DeryaKizilel, RizaDemirel, A. LeventKizilel, Seda
Shear thinningViscosity versus shear rate curves have been measured up to 107 s1 for a range of VM solutions and fully formulated oils of known composition at several temperatures. This shows large differences in the shear thinning tendencies of different engine oil VMs. It has been found that ...
The shape of the molecules in a fluid can also affect the viscosity. Rounder molecules can roll past each other more easily than molecules with branches and less uniform shapes. (Imagine pouring a bucket of marbles out versus pouring a bunch of jacks.) ...
Temperature versus fluid viscosity in a 20,000-ft vertical well after four bottom-ups of circulation at 200 gpm. The hole and pipe size are 8.625 in. and 4.5 in., respectively. Mud weight is 10 ppg. The formation lithology is shale. Heat conductivity of the fluid is 0.392 Btu/ft h ...
A plot of “ηinh” versus “c” and another of “ηred” versus “c” must be done in order to get the intrinsic viscosity at 25°C by means of the extrapolation of both plots to zero concentration [10]. The extrapolated curves will cross each other at the same point on the ...
This paper discusses the thixoforming load versus displacement curves of HP9/4/30 steel semi-solid slugs under compression. The data from the corresponding load-displacement curves is converted into viscosity against shear rate adopting Stefans equation for flow between two parallel planes. The ...
Here, the specific gravity increases significantly, which results in a measured increase of 1.5 percent in kinematic viscosity, versus a 10 percent increase as measured with an absolute viscometer. This is a significant difference that could lead the analyst to identify the situation as nonreportable...
Shear rate (γ˙) is the rate of change of the shear strain with time; also known as rate of shear strain. Shear stress (τ) is the component of a stress that causes successive parallel layers of a material to move relative to each other. ...
