The viscosity of the mixture, owing to the proteins, gelatin or egg albumin, prevents collapse of the air-filled cells.

Ballistic gelatin closely simulates the density and viscosity of human and animal muscle tissue, and is used as a standardized medium for testing the terminal performance of firearms ammunition.

The average density of granite is between 2. 65 and 2. 75 g / cm < sup > 3 </ sup >, its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3-6 • 10 < sup > 19 </ sup > Pa · s.

* Group I – Saturates < 90 % and / or sulfur > 0. 03 %, and Society of Automotive Engineers ( SAE ) viscosity index ( VI ) of 80 to 120

In this book he describes radical nanotechnology as a deterministic / mechanistic idea of nano engineered machines that does not take into account the nanoscale challenges such as wetness, stickness, brownian motion, high viscosity ( Drexler view ).

* ν-kinematic fluid viscosity: ν = μ / ρ, s < sup >− 1 </ sup >

Liquid helium also has this property, but, in the case of He-II, the flow of the liquid in the layer is not restricted by its viscosity but by a critical velocity which is about 20 cm / s.

Heliox has a similar viscosity to air but a significantly lower density ( 0. 5 g / l versus 1. 2 5g / l at STP ).

The advantage of this method over the freq / viscosity versus K-factor method is that it takes into account temperature effects on the meter.

It is also possible to analyse the eluent flow continuously with RI, LALLS, Multi-Angle Laser Light Scattering MALS, UV, and / or viscosity measurements.

:* μ is the dynamic viscosity ( N s / m < sup > 2 </ sup >),

Several school experiments often involve varying the temperature and / or concentration of the substances used in order to demonstrate the effects this has on the viscosity.

Since each of these materials – bitumen, coal tar, pine tar, pitch – is a complex mixture of hydrocarbons, its viscosity / temperature characteristics can vary greatly, depending on how it was made and treated, though pitch is by definition darker and thicker than tar.

Because bitumen flows very slowly, if at all, toward producing wells under normal reservoir conditions, the sands must be extracted by strip mining or the oil made to flow into wells by in-situ techniques, which reduce the viscosity by injecting steam, solvents, and / or hot air into the sands.

The typical smoke generator consists of a pressurized container holding a low viscosity oil such as Chevron / Texaco " Canopus 13 " ( formerly " Corvus Oil ").

| oilsystem = Dry sump, pressure feed @ 5kg / cm² ( 70psi ), 20. 5 centistokes ( 100S. U. secs ) viscosity oil

Stribeck and others systematically studied the variation of friction between two liquid lubricated surfaces as a function of a dimensionless lubrication parameter ηN / P, where η is the dynamic viscosity, N the speed ( e. g. revolutions per minute of a bearing ) and P the load projected on to the geometrical surface.

Whether the anti-settling additive is nanosphere-based or surfactant-based, their addition decreases the packing density of the ferroparticles while in its activated state, thus decreasing the fluids on-state / activated viscosity, resulting in a " softer " activated fluid with a lower maximum apparent yield stress.

There is also an interesting case where the viscosity decreases as the shear / strain rate remains constant.

where σ is the stress, η is the viscosity of the material, and dε / dt is the time derivative of strain.

Other optical techniques are also used: Fluorescence Correlation and Cross-Correlation Spectroscopy ( FCS / FCCS ) can be used to gain information of fluorophore mobility in the membrane, Fluorescence Resonance Energy Transfer ( FRET ) can detect when fluorophores are in close proximity and optical tweezer techniques can give information on membrane viscosity.

This decreases the viscosity of the fluids, thereby also decreasing the pumping / transportation costs.

Heavy crude oil / bitumen are fluids with high viscosity, especially at low temperatures.

Hyh effort is opposed by the viscosity of the water, or utilizing cylinders / equipment where resistance is a function of speed – the faster the movement, the greater the resistance.

kinematic viscosity ( viscosity / density )

The viscosity of cytoplasm is roughly the same as pure water, although diffusion of small molecules through this liquid is about fourfold slower than in pure water, due mostly to collisions with the large numbers of macromolecules in the cytosol.

A small amount of additional tuning is available by ' entry save ' techniques, whereby underwater movements of the upper body and arms against the viscosity of the water affect the position of the legs.

Crick began a Ph. D. research project on measuring viscosity of water at high temperatures ( which he later described as " the dullest problem imaginable ") in the laboratory of physicist Edward Neville da Costa Andrade at University College, London, but with the outbreak of World War II ( in particular, an incident during the Battle of Britain when a bomb fell through the roof of the laboratory and destroyed his experimental apparatus ), Crick was deflected from a possible career in physics.

Gelatin forms a solution of high viscosity in water, which sets to a gel on cooling, and its chemical composition is, in many respects, closely similar to that of its parent collagen.

Since air and water are governed by similar fluid equations, albeit with vastly different levels of viscosity, density, and compressibility, the hydrofoil and airfoil create lift in identical ways ( see foil ( fluid mechanics )).

The viscosity of honey is affected greatly by both temperature and water content.

Above its melting point, however, water has little effect on viscosity.

Aside from water content, the composition of honey also has little effect on viscosity, with the exception of a few types.

Some of these experiments resulted in what was seemingly a new form of water with a higher boiling point, lower freezing point, and much higher viscosity than ordinary water, about that of a syrup.

For example, ketchup can have its viscosity reduced by shaking ( or other forms of mechanical agitation, where the relative movement of different layers in the material actually causes the reduction in viscosity ) but water cannot.

Dissolution of water drastically reduces melt viscosity.

At 20. 00 degrees Celsius the viscosity of water is 1. 002 mPa · s and its kinematic viscosity ( ratio of viscosity to density ) is 1. 0038 mm < sup > 2 </ sup >/ s.

The cylindrical shape of flagella is suited to locomotion of microscopic organisms ; these organisms operate at a low Reynolds number, where the viscosity of the surrounding water is much more important than its mass or inertia.

Variations usually achieved as the result of different method and duration of fermentation, different on ratio of water, salt and fermented soy, different thickness or viscosity, as well as addition of other ingredients.

The angles in this pattern are not intrinsic properties of water ; Any isentropic and incompressible liquid with low viscosity will exhibit the same phenomenon.

The boundary layer development, breakdown, and separation become critical because the high viscosity of water produces high shear stresses.

The eighth drop fell on 28 November 2000, allowing experimenters to calculate that the pitch has a viscosity approximately 230 billion ( 2. 3 ) times that of water.

The viscosity arises from the multiple hydrogen bonds between the dissolved sugar, which has many hydroxyl ( OH ) groups, and the water.

For example, a space game may need simulated gravity, but would not have any need for simulating water viscosity.
