Temperature control is critical to obtaining reliable measurements of dilute solution viscosity, and thus mounting the viscometer in a water bath controlled to +/− 0.01 °C is ideal. Any solvents or solutions going into the viscometer must be passed through a 0.1 μm pore size filter or ...
Temperature: 180 °F Gas specific gravity: 0.65 Air = 1 Mole fraction of N2: 0.1 Mole fraction of CO2: 0.08 Mole fraction of H2S: 0.02 Solution: Pseudocritical pressure = 697.164 psia Pseudocritical temperature = 345.357 °R Uncorrected gas viscosity at 14.7 psia = 0.012174 cp N2 correc...
The next thing to understand is that viscosity is not one quantifiable measurement. It is the flow (velocity) relationships between the substance (glue) and the container it is in (like a desk and board) and the pressure the substance is under. It is also related to the temperature. Whethe...
By timing the fall of a sphere through different known grades of oil, your students can construct a time vs. viscosity graph. This graph is then used to determine the viscosity of an unknown oil. The five tubes of oil are sealed with two spheres, one steel and the other a polymer with...

graph, thism0property can be viewed as the slope of a viscosity–temperature graph [21]. On a microscopic level, the coefficient is said to be a function of several physical characteristics of the fluid such as molecular interlocking, packing, rigidity, and temperature. However, it can also ...
FIELD: oil and gas industry.;SUBSTANCE: method involves arrangement of an fibre-optic cable in a production well; determination of well shaft temperature; build-up of a temperature vs. well depth graph; indication on the graph of a temperature rise minimum by 10 degrees, which is the closest...
temperature was varied from around 70" to 170* F. With the old type of valve it will be seen that the volume flow through the valve increased very rapidly with the increase in temperature as shown by the dotted line on the graph. In contrast to this, the new type of valve with the ...
