1.10. Mathematical equations for boundary conditions

Try these first

1. 1.

   Define what a boundary condition is.

   Hint

   Think about the limits or constraints of a system's boundaries.

2. 2.

   What is a velocity potential?

   Hint

   Consider what represents flow in potential flows.

3. 3.

   What is a boundary condition?

   • Constraint in fluid mechanics
   • Temperature measurement
   • Pressure reading

   Hint

   Think about what specifies conditions in fluid dynamics.

4. 4.

   Kinematic boundary conditions relate to:

   • True
   • False

   Hint

   Reflect on the meaning of kinematic parameters.

5. 5.

   Analyze a system where water is flowing in from an open inlet at 5 meters per second while facing a fixed wall. Define the boundary conditions and derive an equation representing the flow behavior.

   Hint

   Focus on how to apply the inlet's speed and the zero velocity at the wall.

6. 6.

   Given an incompressible fluid flow represented by the Laplace equation, what would happen if one of the boundary conditions is no longer met, like a leaking tank, in terms of unique solutions?

   Hint

   Think about the implications of breaking physical constraints.
