It is well known that the viscosity of a liquid is a measure of its resistance to shear. Upon the introduction of small solid objects into a viscous medium, the internal motion of the liquid when caused to flow is made more complicated than it would be otherwise and the resistance to shear is thereby increased. Einstein (4) has derived the following formula relating the viscosity of a suspensio...

invert sugar is the result of sucrose of hydrolysis of sucrose by acid or enzyme, that is, the splitting of sucrose molecules into their glucose and fructose components.invert sugar is used in different industries such as; food industry, soft drinks and pharmaceutical, due to its special characteristics such as; sweetness level, moisture ability’s property, crystallization level and special tas...

Soils at critical state are like a visco-plastic fluids, which will flow for applied stresses greater than the critical state (CS) shear strength. Shear viscosity is a key parameter to understand the post-failure flow response of soils in geotechnical applications such as landslides, jacked piles and cone penetrometers. Viscosity of soil has been investigated for water contents greater than the...
