Q7. Fill in the blanks.

1. The dimension of shear stress and momentum flux is same, which are both [ ].

2. For the Newtonian fluids, Shear stress is proportional to [ ].

3. In the case of no-slip condition, the fluid velocity at the interface of fluid/solid is [ ].

4. The criteria for the turbulent flow is Re > [ ], while the criteria for the laminar flow is Re < [ ].

5. [ ] is a line that is tangent to the velocity vector of the fluid at each point along the line.
