Kinematic viscosity is obtained from dynamic viscosity by

  • A.dividing by the density
  • B.multiplying by the density
  • C.dividing by the temperature in kelvin
  • D.multiplying by the viscosity index

Answer: A

The kinematic quantity has units of area per unit time, the centistokes in which oils are normally graded, and it is what a capillary viscometer measures directly. The dynamic value in pascal seconds follows by multiplying back by the density.
