OpenStax. Learning Objectives. By the end of this section, you will be able to: Define laminar flow and turbulent flow. Explain what viscosity is. Calculate flow and resistance with Poiseuille’s law. Explain how pressure drops due to resistance. Laminar Flow and Viscosity.
Resistance to flow or resistance that one part of a fluid offers to the flow of another part of a fluid In simple terms: stickiness of liquid Internal friction of molecules Present in ideal gases, real gases, liquids momentum transfer causes the so-called internal friction in our fluid and prevents it from flowing in a particular direction ...
The laminar flow through a pipe is described by the Hagen-Poiseuille law, stating that the flow rate (F = volume of fluid flowing per unit time) is proportional to the pressure difference Dp between the ends of the pipe and the fourth power of its radius r.
Calculate flow and resistance with Poiseuille’s law. Explain how pressure drops due to resistance. Laminar Flow and Viscosity. When you pour yourself a glass of juice, the liquid flows freely and quickly. But when you pour syrup on your pancakes, that liquid flows slowly and sticks to the pitcher.

30 Ιαν 2023 · Viscosity can be not only a fluid’s resistance to flow but also a gas’ resistance to flow, change shape or movement. The opposite of viscosity is fluidity which measures the ease of flow while liquids such as motor oil or honey which are “sluggish” and high in viscosity are known as viscous.
