Comments

• Some students did not answer which type of pressure drop is measured by the manometer (P2.44).

• Some students did not multiply the shear stress (F/L2) by the area in order to find the shear force (F). They used the shear stress as a force (P1.41 and C1.4).

• Some students used directly the Navier-stokes equation to find the viscosity instead of a force balance between weight of fluid and shear force (C1.4).

• 72% of the undergraduate students attempted to solve the comprehensive problem, generally with good results.
