RHEOLOGY FORMULAS

Question 1

DETERMINATION OF RHEOLOGIC PROPERTIES

viscosity of liquid using Capillary viscometer
aka Ostwald visometer

Answer 1

ηγ = (ηw) (ργ) (tγ) / (ρw) (tw)
ηw = theoretical viscosity of water 0.890
ργ = theoretical density of the sample
ρw = theoretical viscosity of water 0.997
tγ = time of flow sample
tw = time of flow water
