The unit of coefficient of permeability in the SI system is:
Correct answer: B. m per second
- A. square metres per second
- B. m per second
- C. kilonewtons per cubic metre
- D. cubic metres per second
Explanation
The coefficient of permeability represents the velocity associated with a unit hydraulic gradient, so its SI unit is length per time, or metres per second. Square metres per second is a unit of consolidation or diffusion-type coefficients.

About Soil Mechanics and Foundations
Soil mechanics examines index properties, phase relationships, classification, permeability, seepage, compaction, consolidation, shear strength and earth pressure. Foundations apply these principles to bearing capacity, settlement and shallow or deep foundation selection, with clear distinction between compaction, which expels air, and consolidation, which expels water over time.
