Question 1.
What is the no-slip boundary condition?
Show hintHide hint
Think about how water behaves at rest against a surface.
Question 2.
Define the boundary layer.
Show hintHide hint
Consider how fluid velocity changes close to surfaces.
3Question 3.
What is the no-slip boundary condition?
- The velocity at the boundary is always zero
- Fluid velocity is less than boundary velocity
- Fluid sticks to the boundary
Show hintHide hint
Think about water sitting still against a wall.
4Question 4.
Turbulent flow occurs when the Reynolds number exceeds what value?
Show hintHide hint
Remember the critical number for flow transition!
Question 5.
A flat plate in a flow has a free stream velocity of 10 m/s. If the kinematic viscosity is 1 x 10^-6 m²/s, calculate the Reynolds number at a distance of 0.5 m from the leading edge.
Show hintHide hint
Use the Reynolds number formula to solve.
Question 6.
Discuss how the environmental factors such as viscosity and temperature may affect the boundary layer development in a given fluid system.
Show hintHide hint
Consider how real-world applications like cooling and heating impact flow.
