where ρP is the particle density, VP is the particle volume and ρ˜ is the effective density of the composite fluid. There is a controversy about the effective density in the case when the fluidized solid particles have the same volume VP and density ρP as the test particle with drag D given by (1).

High-pressure capillary viscometers with electric drive . Such a viscometer works in the same way as a weight-driven instrument (see the above section). However, the weight is replaced by a driving motor, which realizes high shear stress values (up to 900 kPa) and medium to high shear rates (around 1,500 s-1). Typical applications are highly ...

From the Mark-Houwink equation, the relationship among the molecular weight and viscosity is given below: , where is the intrinsic viscosity (dL/g), is molecular weight (Dalton), and and are constants for a particular polymer-solvent system (and are 3.73*10 −4 and 0.66 in 1 N aqueous sodium nitrate at 30°C) [21, 24].

Sep 01, 2015 · During this process, water soluble polymers are added to flooding water and then injected into reservoirs. Polymer flooding increases water viscosity and oil/water mobility ratio, and thereby enhances oil recovery. Polymer flooding has been proven to be an effective means to enhance oil recovery for middle/high water-cut oilfields . In this respect, partially hydrolyzed …

SINOFLOC supplies our customers a wide range of product portfolio in the oilfield industry. In addition to our standard oilfield chemicals, we are also supplying customized products to our clients in the different condition of high TDS and API brine, as well as in specific particle size.

High pressure homogenization of the pre-emulsion is done above the lipid melting point. Usually, lower particle sizes are obtained at higher processing temperatures because of lowered viscosity of the lipid phase, although this might also accelerate the drug and carrier degradation. Better products are obtained after several passes through the ...

of tests was conducted to study the effect of high temper-ature on polymer viscosity. The test temperature was controlled at 50, 70 and 90 C. The shear rate was con-trolled at 1, 10, 100 and 1,000 s-1. The tested polymer concentration was 1,500 ppm. All viscosity measurements were conducted by a torque-type viscometer.

the viscosity, which is expected to be small but significant for high-molecular-weight polymers such as those used in this work. In distilled water, the Mark-Houwink viscosity parameters for polyacrylamide are K - 6.31 X 103 dl/g and a = 0.8 at 30°C.27 Similar parameters are not available for the acrylamide co-polymers.

Y type globe: The Y-type valves design are used to solve the high-pressure drop problem in Z-type valves. So due to simplifying the problem of Z-type, we configure the Y-type, where seats are angled at 45° to the axis of the pipe. So These valves are used in high pressure and many other reproving services.
