Viscosity is an important fluid property whose importance to many different products in a variety of industries cannot be overstated. What are the factors that affect viscosity? Let's move on.
Fluid viscosity depends on many factors. like:
Fluid temperature: In general, the viscosity of a liquid decreases with increasing temperature. However, the viscosity of a gas generally increases with temperature.
Flow conditions: For laminar flow, the viscosity of the liquid remains constant; while for turbulent flow, the viscosity changes.
Pressure: When the pressure is increased, the viscosity of the gas generally increases. For liquids, since they are incompressible, pressure doesn't have much effect.
Multiphase Flow: The viscosity of a multiphase flow varies by the volume of each phase.
Suspended Particles: Suspended material causing an increase in viscosity.
