Question 1.
What is the main purpose of velocity potential functions?
Show hintHide hint
Think about how many scalar components we typically deal with in fluid flow.
Question 2.
What are the key assumptions made when analyzing incompressible viscous flow?
Show hintHide hint
Consider the flow direction and external forces acting on the fluid.
3Question 3.
What is the primary function of velocity potential functions?
- To define pressure
- To represent velocity fields in irrotational flows
- To calculate mass flow rate
Show hintHide hint
Think about reducing components for simplifying fluid velocity.
4Question 4.
Is the following statement true? Navier-Stokes equations can be approximated under certain conditions.
- True
- False
Show hintHide hint
Recall how assumptions like irrotational flow can aid in simplifications.
Question 5.
Using a scenario where water flows between a fixed and a moving plate, derive the expressions for shear stress and analyze the impact of varying velocities.
Show hintHide hint
Integrate your solutions considering velocity profiles will provide shear values.
Question 6.
Examine how flow around circular objects differs from flow past rectangular structures in terms of rotational effects.
Show hintHide hint
Compare the designs to determine how shapes influence flow separation.
