For example, oil has a high viscosity, but when we put it in the car and heat it up, it becomes less viscous and thus flows smoothly through an engine and other parts of the car. It is defined in terms of the force required to move one plane surface continuously past another under specified steady-state conditions when the space between is filled by the liquid in question. Introduction • A Fluid is a substance which deforms when subjected to a force. As you decrease temperature, you increase a fluid's viscosity.

Two long tubes are filled with fluids of different viscosities, one with water and the other with glycerin. , dynamic viscosity . HVS is the pathological condition in which blood flow is reduced due to an increase in its "thickness" [1,5]. He realized that once specific viscosity was determined, a graph of specific viscosit y v. concentration would allow determination of the limiting viscosity of t he solute. • The greater the friction, the greater the amount of force required to cause this movement, which is called shear. • Measurement of viscosity .

Biopharmaceutical proteins have been widely developed for the last decade [].Recent advances in the protein drugs have resulted in a new type of problems related to the difficulty in handling the protein solutions, typically aggregation [] and viscosity [].To deliver a therapeutic protein, a highly concentrated protein solution is needed for intramuscular and subcutaneous . For calculations, please note: The units for density are kg/m 3 and g/cm 3, where 1000 kg/m 3 = 1 g/cm 3. In these viscometers one of the surfaces is stationary and the other is rotated by an external drive and the fluid fills the space in between. For example: where t is the stress (Pa), is the resulting velocity gradient in the fluid, and q is the viscosity (sometimes referred to as shear . h; (c) Prandtl number Pr and thermal expansion coefficient . This presentation reflects only the views of the . A high-viscosity fluid has a low tendency to flow, whereas low-viscosity fluids flow easily.

Scribd is the world's largest social reading and publishing site. A viscous fluid, such as honey, does not flow readily and is said to have a large viscosity. 6. The coefficient of viscosity of a liquid is defined as the viscous force acting per unit area between two adjacent layers of a liquid such that the velocity gradient is normal to the direction of flow of the liquid. In contrast, water is less viscous and flows more readily; water has a smaller viscosity than honey. Viscosity Index (VI) defines the viscosity relationship with temperature. The SI unit of viscosity is equal to 10 Poise or 1000 centipoise.
