WebbA fluid’s viscosity is a measure of its resistance to flow. It describes the internal friction of a moving fluid. Viscous fluids resist motion because their molecular makeup creates a lot of internal friction. Fluids with low viscosity flow easily because their molecular makeup creates little friction when they are in motion. Webb11 jan. 2024 · One example of a high-viscosity fluid is honey. When an object free falls through a fluid, at some point the force due to gravity is balanced by the resistance to shear by the fluid. This is called terminal velocity, and is the point at which the falling object maintains a constant velocity.

Slow moving liquids have a high viscosity

WebbOn the other hand, the turbulent flow tends to occur at higher velocities and low viscosity. Since the laminar flow is common only in cases in which the flow the channel is relatively small, the fluid is moving slowly, and its viscosity is relatively high. Laminar flow is not common in industrial processes.

Webb18 nov. 2024 · 2. The viscosity of fluid. The viscosity of fluid plays a major role in determining the velocity of the object which flows through it. The more viscous is the fluid the denser it is and hence the movement of any material inside it is restricted or experiences resistance to its motion. The denser is the liquid the more viscous drag it … Webb6 maj 2010 · If lava slows, cools, and stops in direct response to the corresponding increase in viscosity only, it retains its pahoehoe form. If lava is forced to continue flowing after a certain critical relationship> between viscosity and rate of shear strain is achieved, the lava changes to aa.

WebbTypesof°ow.Two broad classes of viscous °ow will be illustrated in this chapter: 1. Poiseuille °ow, in which an applied pressure diﬁerence causes °uid motion between stationary surfaces. 2.
