19 Μαρ 2023 · Overall, this law holds best for non-polar gases such as N 2 and O 2 that do not significantly interact with the water. It does not hold well for a gas like HCl, which ionizes in water to form the hydrated ions H + (aq) and Cl − (aq).
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.
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.
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 ...
Summary. 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. When you pour yourself a glass of juice, the liquid flows freely and quickly.
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.
25 Μαρ 2020 · The viscosity of a fluid is a measure of the internal resistance to flow! It is caused by intermolecular forces and transport of momentum within the fluid. Introduction. If one looks at the flow behavior of water in comparison to honey, large differences are noticeable.
