 One student multiply density to the dynamic viscosity to get kinematic viscosity.

ν = ρμ(x) ν = μ/ρ(o)

 Some of students indicated wrong Unit [Ex)Pa → N/m], or didn’t indicated Unit.

 Several student could not use the velocity profile table correctly.

 Some of students considered only one surface of area when calculating Drag Force.

 A few of students thought that the flow is turbulent condition, so used wrong equation for this problem.
