Reynolds number - Eastern Canada (1)

Question

This quantity was first introduced by George Stokes in 1851, but was named after the scientist who popularized it. For 10 points each:

[10m] What dimensionless quantity equals the ratio of inertial and viscous forces? This quantity is more than a few thousand in turbulent flow.

ANSWER: Reynolds number [or Re]

[10e] This type of flow, contrasted with turbulent flow, occurs at low Reynolds numbers. This type of fluid flow contains layers that move smoothly and experience little or no mixing.

ANSWER: laminar flow

[10h] Assuming laminar flow and this condition, the Hagen–Poiseuille (“HAH-gin pwah-ZOY”) equation gives the pressure drop of a fluid in a pipe. Water approximately obeys this condition in which the divergence of velocity equals zero.

ANSWER: incompressibility [or incompressible flow]
