#### Blasius Solution: Summary

The answers to the ConcepTests are given below and will open in a separate window.

##### Key points from this module:

- The boundary layer thickness can be described as the height in the y-direction where the velocity of the fluid in the boundary layer is equal to 0.99 of the free stream velocity.
- The Blasius solution uses a similarity solution to determine the boundary layer thickness, as well as other parameters in boundary layer flow.
- This solution can be used to find the velocity at any point in the boundary layer.

##### From studying this module, you should now be able to:

- Determine the thickness of a boundary layer.
- Find a velocity at any point in a boundary layer.
- Calculate the boundary layer thickness as a function of the Reynolds number.
