Worked Example
Verified calculation
Given:
- Face velocity at top-left point = 0.5
- Face velocity at top-right point = 0.5
- Face velocity at center point = 0.5
- Face velocity at bottom-left point = 0.5
- Face velocity at bottom-right point = 0.5
- Target face velocity = 0.5
Expected Result:
- Velocity deviation magnitude = 0
Engineering Interpretation:
Under the given input conditions, the calculated result is: Velocity deviation magnitude = 0 m/s.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
Formula / Method
velocity deviation magnitude = sqrt((pow(face velocity at top-left point - target face velocity, 2) + pow(face velocity at top-right point - target face velocity, 2) + pow(face velocity at center point - target face velocity, 2) + pow(face velocity at bottom-left point - target face velocity, 2) + pow(face velocity at bottom-right point - target face velocity, 2)) / 5.0)Formula family: formula_laboratory_fume_hood_face_velocity_profile_deviation_calculator
