![]() The following table provides the dynamic viscosity of water with respect to various temperatures. As for liquids, the viscosity decreases with an increase in temperature, the same is true for water. The viscosity of water at 20 0 C is 1 centipoise or 1 cP. Suspended Particles: Suspended materials increases viscosity.Multiphase flow: The viscosity of multiphase flow is affected by the volume of each phase.Liquids being incompressible does not have much impact. Pressure: With an increase in pressure, the viscosity of gases usually increases.Flow Conditions: For laminar flow, the viscosity of liquid remains constant while for turbulent flow viscosity changes.On the contrary, the viscosity of gases increases with an increase in temperature. Fluid Temperature: Usually the viscosity of liquids decreases with an increase in temperature.There are various factors that affect the viscosity of a fluid. Acoustic rheometer Factors Affecting Viscosity. ![]() So, honey is providing more resistance to motion than water and that is why water is moving more freely than honey. This is because honey is more viscous than water. If we take water and honey in a pot and try to pour, we find that water is flowing more smoothly and quicker than honey. The concept of viscosity will be more clear if we consider the following example. In general, liquids have more viscosity than gases. So, a fluid having large viscosity provides more internal friction to resist flow whereas a fluid with lower viscosity provides little friction. For a fluid in motion, viscosity describes internal friction. In fluid mechanics, Viscosity is defined as the measure of a fluid’s resistance to fluid flow under an applied force. The term “viscosity” has its root in the Latin term “Viscum” which refers to a viscous glue originating from mistletoe berries. Practical Applications of Viscosity Definition of Viscosity.
