Pa·s is equivalent to N × s ÷ m 2 or kg/m/s. Temperature will affect the viscosity of most materials. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. The effect caused by temperature in the range studied was more important in the low range of temperature, whereas at high temperature, the viscosity showed less variation. The viscosity value decreased with the increase of temperature. Dynamic Viscosity The first is dynamic viscosity, also known as absolute viscosity, which measures a fluid’s resistance to flow. In layman’s terms, viscosity defines a fluid’s resistance to flow. Influence of temperature on the viscosity of honeys was analysed in the present work. Higher water content will similarly reduce the viscosity of honey. The pascal-second is a unit of measurement of dynamic viscosity A pascal-second (Pa·s) is a derived metric SI (System International) measurement unit of dynamic viscosity. Viscosity is the result of frictional interactions within a given liquid and is commonly expressed in two different ways. according to Strokes law, to pull a honey spoon, a sphere of diameter 20 mm, out of a jar of honey at a rate of. Conversely heating the honey to (say) 50☌ will greatly reduce its viscosity and improve its ability to flow. Question: The viscosity of honey is 100 Pa s.

On the other hand, fluids that take time to flow, like honey and glycerol, have high viscosities. For example: for every 1 Pascal second (Pa s) increase in viscosity of water. However, the ability of the honey to flow after it is cooled in a refrigerator is greatly diminished. Water has a low viscosity since water can flow readily. Honey is characterized by its thick consistency, which is a direct result of its very strong intermolecular forces. Honey in a jar will flow at room temperature, albeit slowly. Not so fast! Viscosity can be described as the ability of a fluid to flow over itself, and it can be highly dependent on temperature. The first viscosity appears to be a generic estimate whereas the second refers to a specific commercially available product.Īnswer E appears to be correct. More research reveals that blended flower honey has a viscosity of approximately 12,200 cP at the same temperature. Using a theory that describes how bubbles and droplets coalesce, the team inferred an extremely high viscosity of around 3000 pascal-seconds for the nuclear fluid (honey’s viscosity is about 10 pascal-seconds, while water’s is 0.001 pascal-seconds). What is the approximate viscosity of honey in centipoise (cP)?Ī quick internet search shows that the viscosity of honey is 10,000 cP at a room temperature of 21.1☌.
