Rheology Flashcards
1
Q
Give an equation to calculate the dynamic viscosity of a liquid
A
F/(dv/dr)
shearing stress/rate of shear
2
Q
Relate viscosity and internal forces
A
When internal forces are high, viscosity increases.
3
Q
How does temperature affect viscosity of liquids?
A
As temperature increases, viscosity decreases
4
Q
Give an equation of the effect of temperature
A
log(eta) = {E/R x 1/T} + log(A)
5
Q
Give an equation that relates to capillary viscometers
A
eta = KtDeltaP
