Question 1

dynamic viscosity

Answer 1

measure of fluid’s resistance to flow

tangential force per unit area required to maintain a difference in velocities of 1m/s btw 2 parallel layer of liquid 1m apart

Question 2

kinematic viscosity

Answer 2

ratio of viscosity of a fluid to its density

Question 3

Newtonian fluid

Answer 3

viscosity of fluid is independent of shear rate, obeys Netwon’s law of friction

Question 4

viscometer

Answer 4

tool used to measure viscosity using relationship btw shear stress and shear rate
