![]() ![]() ![]() Other rheological properties such as kinematic viscosity and fluidity,Ĭonclusion: All the honey samples behaved as Newtonian fluids in the whole temperature range. This model was used to determine the activation energy. Arrhenius model was used to describe the effect of temperature on the honey viscosity. A honey containing 16 humidity, at 70 ☌ (158 ☏), will have a viscosity of around 2 poise, while at 30 ☌ (86 ☏), the viscosity will be around 70 poise. Results and Discussion: The honey samples of lower moistureĬontent showed a greater increase in their apparent and dynamic viscosities. The apparent viscosity was measured by Brookfield Viscometer, and the dynamic viscosity was measured by HAAKE Falling Ball Viscometer, after changing the temperature from 293 to 323 K. To get the kinematic viscosity (in centiStokes), just divide by the specific gravity of the fluid. Viscosity is given in centiPoise (cP), equivalent to milliPascal seconds (mPa s). Tension varied from 0.2178 to 0.2282 N/m. Table of Viscosities A compiled list of viscosities of various materials. The specific heat capacity varied from 2448.078 to 2575.004 J/kg.K. The volumetric expansion coefficient of the honey samples varied from 6.0098x10-4 to 6.69942x10-4 mm3/K. The linear relationship between the electrical conductivity and theĪsh content was also calculated in this investigation. The electrical conductivity ranged from 40.896 to 44.471 mS/cm. The moisture content, soluble solids, and refractive index ranged from 15.60 to 16.60 g/100 g, 83.40 to 84.40, and 1.4998 to 1.5023, respectively. honey viscosity has been determined at a constant value of shear rate (1.4 s1). The pH and free acidity of the honey samples varied from 4.10 to 4.81 to 30 to 62 mEq/kg, respectively. Index, soluble solids (Brix), electrical conductivity, volume expansion, density, specific heat capacity, surface tension, and rheological properties. Methods: The honey samples were analyzed for pH, free acidity, total ash content, moisture content, refractive Aims: In this study, the physical and rheological properties of three poly-floral honey samples collected from different places in the Kurdistan region were determined. ![]()
