Rheology

If we go in the depth of the flow of matter that we called Rheology; It include fluids, soft solids like gels, pastes, paints, ketchup and variety of other items. Rheology put on elements that have difficult structure like mud, sludges, suspensions, polymers, petrochemicals and biological materials. Flow of these complex elements cannot be distinguished with the one value of viscosity. With the change in the conditions of elements viscosity also changed.
For instance; when we shake the ketchup its viscosity level become low. when Cornflour stuck its viscosity level increase. 

In routine,Rheology is concerned with the componentswho’sproperties are between purely elastic material and Newtonian fluids, it is the point where the mechanical behavior can’t define by the classic theories.

The device that is used for measuring the Viscosity &Rheology is known as Rheometer. Now day’s there are variety of Rheometer available in Markets. Let’s put some light on the rotational Rheometer.

Rotational rheometer is the most common type of rheometer which is capable of testingRheology ofnumerous applications by which we can easily characterized elements.  It is a simple device in which a single rod revolves in a single direction. This type of rheometeris highly appropriate for the quality testing. A port is attached with this rheometer by which we can easily measure the Rheology of component in the field. For evaluating the samples having low Viscosity&Rheology we commonly prefer to use low friction air bearings.

Viscometer and Rheometer both are complimentary devices for measuring Viscosity&Rheology and it is not unusual to see Viscometer and Rheometerin a single lab Or organization.

Severe blood loss treated with Hyper-Viscosity

Researchers from UC San Diego have come up with a radically different solution for severe blood loss treatment. In their study, fluids with much higher salt content than conventional saline are combined with viscosity enhancers with the purpose of thickening blood.
Increasing blood viscosity would seem the wrong approach to restore flow through tissues. However, results based on animal trials suggest that enhancing blood viscosity significantly increases functional capillary density, a key parameter in healthy blood flow through tissues and organs. This resulted in an increase in resuscitation rates after severe blood loss was induced.

This seemingly contradictory effect is explained by an increase in size of small blood vessels (dilation) caused by the higher shear stresses exerted by the blood with higher viscosity after treatment.

Why Industries Measure Viscosity

A huge number of industries used viscometer now days to measure the viscosity of liquid’s. For a product to be useful, it is necessary to maintain their qualities and nature. Grease melted on high temperature in the machine shops that’s why grease don’t stick to the surface as required that is the reason companies manufacture the grease must need to identify the several viscosity rates in proportion to the temperature on which it is tested. By measuring the viscosity using the viscometer will help industries to generate the products that will satisfy their clients in better way and consistent in quality. Most of times the viscosity data is collected for detecting, observing other attributes of the material because when we know some other properties of material it is easier for us to measure the viscosity. Hence it is very significant tool for characterization of the material.

 

Viscosity - RheoSense

Viscosity can be defining as resistance of fluids to flow at a specified temperature. The fundamental benefit of the technology is that it empowered us for the discovery of new devices. Rehometer is from one of that devices. Fundamentally Rehometer is use in a branch of physics know as  Rheology which use in calculating the flow of fluids. For instance, the time when force is implement on liquid slurry or suspension, their behavior will be different with different quantity of force. The Rheometer facilitate us to calculate it. That slurry liquid includes many substances like mud, polymers, blood etc. Rheometer is the only device that measure all the parameters and values of these liquids particularly the Viscosity. Rheometers are classify in two types based on their use and applications.

• Shear rheometers
• Extensional rheometers

All these devices may have the same aim but the applications and the external forces differs as said by the parameters of the fluid that are to be measured. For measuring the Viscosity & Rheology of the substance Shear rheometers or rotational rheometers are sub categorize on the bases of needs of application that are mention below

• Pipe Rheometers
• Capillary Rheometers
• Rotational Cylinder
• Cone and plate Rheometers
• Liner shear Rheometrs

Each type is specified for specific number of substance. This specification is based on the nature of the substance along with accuracy rate of Viscosity & Rheology at specified temperature level. Viscosity is measured in different Industries like food industry, Pharmaceutical Industries and many more. In food industry Viscosity is mostly measured for maintaining the quality of the product. Temperature plays a vital role in measuring the Viscosity & Rheology of any substance. A minor change in temperature may affect the results of Viscosity plus Rheology.

Plasma Viscosity - RheoSense

We can define Plasma Viscosity as the indirect measure of the quantity of protein existing in the plasma. Plasma Viscosity can reflect the level of swelling existing in the body. Plasma Viscosity can also identify the existence of abnormal paraproteins that can be built by benign or malignant cancer. Plasma Viscosity basically calculate the quantity of the force required to send a calculated amount of the plasma moving along a slender tube in a provided time at a regular temperature. Usually purified water at 20 degrees Celsius will have viscosity of 1.00mPas (mili-Pascal-second), when in fact standard plasma at 37 degrees Celsius possibly have the viscosity of approximately 1.7mPas. As the results gone higher stickier the blood is. Greater than before the blood level of certain proteins for instance fibrinogen, that is grow in swelling or immunoglobulins, which increased swelling or unseen by some tumours, become the reason for increasing of Plasma Viscosity.

Plasma Viscosity is used to observe the similar situation or circumstances that the ESR (Erythrocyte Sedimentation Rate) is. However, Plasma Viscosity is better test as compare to ESR, Plasma Viscosity is complex to perform and is not used on large scale. 

Plasma Viscosity can be used to observe severe and long-term swelling, because of infections, cancers and autoimmune diseases. It is said that the Plasma Viscosity is not specific because intensifications don’t tell the doctors accurately rather the reason is a paraprotein or swelling. Fundamentally for this causes an abnormal Plasma Viscosity is usually followed by the other tests.

Two specific swelling diseases temporal arthritis and polynomial rheumatic are identifying with the help of the Plasma Viscosity. A High Plasma Viscosity is one of the key test result that is used to ensure the diagnosis. High Plasma Viscosity is also used to observe activity of the diseases and response to therapy in both of these diseases.

Viscometer

Viscosity also has a vital role in the food industry, for this Viscometer widely used in food industry. With the passage of the time the demand of the high quality food is increasing day by day and high quality food get an important place in the life of people. Manufacturing products in the food industries that fulfill huge demand of the users become challenging for the analysts. For competing these challenges analysts speedily reacts to overcome problems and that reaction must be 100 % accurate, and should not be costly. Majority of all that actions relates to the physical measuring like viscosity after that the selection of Viscometers.

Viscosity have a major role in all kind of the industries in which liquid is involved. If we say that viscosity have approximately have a role in each stage of the food industry, it should not be wrong. For instance, a huge range of liquid media have to cautiously inject by tubes. The viscosities in this segment range from fluid to pale.

In food industry verity of sugar is used on regular basses like glucose syrup its simple mean that they must have verity of Viscometer to measure the viscosity of products in which different verity of sugar used. Numerous sorts of syrup are gotten from enzymatic degradation of starch and are major items for the starch Industry. From the time the syrups are gluey it is commonly used as binder in the food products like sauces and the chocolates. The food product that contain starch, viscosity of that products is totally depend on the glue properties of the starch. Therefor in such cases for the section of Viscometer & know Viscosity of such products we first know that which type of starch is used in the product.
