The distorted models used in the hydraulic studies are those which
- Ahave exaggeration of the vertical scale and horizontal scale.
- Bare not geometrically similar to the prototypes.Correct
- Chave same vertical and horizontal scale as that of the prototypes.
- Dhave same Froude number as that for the prototypes.
Solution
Concept
Distorted model
Step-by-step solution
1. Distorted models have different horizontal and vertical scales.
Explanation
They are not geometrically similar.
Why the other options are wrong
Same scales give undistorted models.
Shortcut
Distorted = not geometrically similar.
Correct answer: B) are not geometrically similar to the prototypes.
