Kinematic viscosity and water activity of aqueous solutions of glycerol and sodium chloride. European Food Research and Technology 219, 403-408.Chenlo, F.; Moreira, R.; Pereira, G.; Bello, G. Kinematic viscosity and water activity of aqueous solutions of glycerol and sodium chloride. European ...
During osmotic dehydration, a removal of water from foodstuffs is achieved with a decrease in the water activity of the food sample. This dehydration process involves the utilization of highly concentrated solutions with one or several solutes that increase considerably the viscosity of the liquid phas...
Water at 20 °C has a kinematic viscosity of about 1 cSt. The kinematic viscosity is sometimes referred to asdiffusivity of momentum, because it is analogous to diffusivity of heat and diffusivity of mass. It is therefore used in dimensionless numbers which compare the ratio of the diffusivities...
The binary experimental data were used to adjust the parameters of a Kumar-like equation. Relative errors around 5.5% were observed between calculated and experimental results. The adjusted parameters also allowed the viscosity prediction for multicomponent mixtures, with an overall deviation of 9.9%....
Equation(1)is known as theNewtons Law of Friction. (1)can be rearranged to expressDynamic viscosityas μ=τ dy / dc =τ / γ (1b) In theSI systemthe dynamic viscosity units areN s/m2,Pa sorkg/(m s)- where 1 Pa s = 1 N s/m2= 1 kg/(m s) = 0.67197 lbm/(ft s) = 0.0...
μ, dynamic viscosity [Pa · s] γ̇, shear rate 1s While the effect of pressure below p < 1000 bar is negligible (Siegloch, 2009) in a common stirred bioreactor with aqueous broth the effect of temperature is often prevailing. As an example, the viscosity of pure water at 20 °C ...
The kinematic viscosity and density of binary aqueous solutions containing xanthan gum and ternary aqueous solutions containing carboxymethyl cellulose and sodium chloride have been measured from 303K to 318K at different values of pH. The viscosity and density for binary and ternary systems showed incr...
