## Blasius equation Solution

STEP 0: Pre-Calculation Summary
Formula Used
friction_factor = (0.316)/(Reynolds Number^(1/4))
f = (0.316)/(Re^(1/4))
This formula uses 1 Variables
Variables Used
Reynolds Number- The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.

### FAQ

What is Blasius equation?
The Blasius equation formula is defined as the steady two-dimensional laminar boundary layer that forms on a semi-infinite plate that is held parallel to a constant unidirectional flow and is represented as f = (0.316)/(Re^(1/4)) or friction_factor = (0.316)/(Reynolds Number^(1/4)). The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.
