Question 1: What does the following picture show?

  Structure evidenced in a typical linear (non-branched) polymer found in a fossil fuel like petroleum.
  Linear structure of cellulose -- the most common component of all organic plant life on Earth. * Note the evidence of hydrogen bonding which increases the viscosity at any temperature and pressure. This is an effect similar to that of polymer crosslinking, but less pronounced.

  Lava flow during a rift eruption at Krafla, Iceland (1984).

Question 2: vs - mean fluid ________, [m s-1]
SpeedKinematicsClassical mechanicsVelocity

Question 3: Such relationships are then amenable to mathematical treatment by the established methods of ________.
Continuum mechanicsFluid mechanicsFluid dynamicsViscosity

Question 4: Under low Reynolds numbers viscous effects dominate and the flow is laminar, whereas at high Reynolds numbers inertia predominates and the flow may be ________.
