Also know, what is the relationship between viscosity and velocity?
Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them. Formally, viscosity (represented by the symbol η "eta") is the ratio of the shearing stress (F/A) to the velocity gradient (∆vx/∆z or dvx/dz) in a fluid.
Likewise, what are the factors affecting viscosity? Viscosity is resistance to flow. For liquids, typically the larger the intermolecular forces (IMF) the higher the viscosity. The other factors that affect viscosity are temperature and the shape of the molecule. Higher temperatures will correspond to higher average kinetic energies and faster moving molecules.
Consequently, does viscosity change with velocity?
The viscosity of Newtonian fluids is affected by temperature, pressure, and, in the case of solutions and mixtures, by composition. For Velocity effect, you should know that, fluid deforms continuosly ,rate of deformarion is something euivalent to rate of change of velocity w.r.t film thickness.
How do you find velocity from viscosity?
There are several formulas and equations to calculate viscosity, the most common of which is Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.
