Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFShear velocity:
- It is also known as frictional velocity is fictitious quantity, and it characterizes the shear at the boundary.
- The shear velocity characterizes the turbulence strength and laminar sub-layer thickness.
- It relates shear stress in terms of velocity and is given by \(\sqrt {\frac{{{\tau _o}}}{\rho }} \)
- ∴ Shear velocity \(u* = \sqrt {\frac{{{\tau _o}}}{\rho }}\) .
