How to Perform the 0.4 Velocity Profile Method?
Summary
Performing the 0.4 Velocity Profile Method.
Answer
The 0.4 method is a simplified version of the 0.2, 0.4, 0.8 method. The velocity is measured at
the 0.4 position only.
 
To profile the flow:
1. Measure the depth of flow
2. Calculate the measurement positions on the center line:
• .4 position = 0.4 x depth of flow
3. Measure the velocities at the .4 position.
