Viscosity: Fluids with high viscosity offer more resistance than the ones with low viscosityTemperature: As the temperature increases, the viscosity of liquids decreases, whereas the viscosity of gases increases.Pressure: With an increase in pressure, the viscosity of liquids increases, except water. The viscosity of gases is unaffected.
Different for different fluidsIndependent of the load or pressureReduced with the increase in temperatureDependent on the velocity of the flowProportional to the surface area of contact
