Detailed explanation-1: -Liquids that have a HIGH viscosity flow slowly (ie. honey, corn syrup, and molasses). Viscosity can also be thought of as a measure of how “thick” a liquid is. The more viscous (or thick) a liquid is, the longer it will take for an object to move through the liquid.
Detailed explanation-2: -Viscosity is the measure of resistance of a fluid to flow. A fluid that is highly viscous has a high resistance (like having more friction) and flows slower than a low-viscosity fluid.
Detailed explanation-3: -Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly; high viscosity fluids move sluggishly and resist deformation.
Detailed explanation-4: -A frequent question regarding peristaltic pumps is how viscosity affects flow rate. The short answer is; as viscosity increases, flow rates decrease.
Detailed explanation-5: -Viscosity is a measure of a fluid’s resistance to flow. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.
