The formula for Dynamic Viscosity. Since dynamic viscosity is the tangential force required to move one horizontal plane of a fluid with respect to another. Thus, we can express it as: Dynamic viscosity = \(\frac {shearing stress} { shearing rate change}\) In the form of the equation, we can write it as: \(\eta = \frac {T}{\gamma }\) Where, \(\
Calculate the viscosity of a mixture (air) made of 20% oxygen, \(O_2\) and 80% nitrogen \(N_2\) for the temperature of \(20^{\circ}C\).
Dynamic Viscosity. The first is dynamic viscosity, also known as absolute viscosity, which measures a fluid’s resistance to flow. In precise terms, dynamic viscosity is the tangential force per unit area necessary to move one plane past another at unit velocity at unit distance apart.

Mathematically, dynamic viscosity can be expressed as: μ = τ dy / dc = τ/γ . Where: τ = shearing stress in fluid (N/m 2). μ = dynamic viscosity of fluid (N s/m 2). dc = unit velocity (m/s). dy = unit distance between layers (m). γ = dc / dy = shear rate (s-1). The SI unit for dynamic viscosity is N s/m 2 or the Pascal-second
In this calculator, you will learn what the absolute viscosity of water is (commonly known as its dynamic viscosity) and how to convert it to kinematic viscosity. You will also learn how to calculate the viscosity of water and the effect of temperature on the viscosity of water using various methods.
Dynamic viscosity is typically measured in units of Pascal-seconds (Pa·s) or poise (P), with 1 P equaling 0.1 Pa·s. The dynamic viscosity of liquids generally decreases with increasing temperature, while for gases it tends to increase.
8.5: Dynamics- Viscous Fluids. The viscosity of many fluids, at not overly high velocities, may be described surprisingly well by adding, to the static stress tensor (2), additional components proportional to the velocity v ≡ dq / dt : σij = − Pδij + ˜σjj(v).
