Expert Solution
Step 1

Objective: To determine the depth of river for the given flow to be turbulent.

 

Given:

Flow velocity (u) = 0.05 m/s

Kinematic viscosity (ν) = 1×10-6 m2/s

 

Reynold's number (Re) is defined as the ratio of the inertial forces to the viscous forces acting on a fluid. Reynold's number for open channel flow can be given as:

Re=u×Rhν

here,

Rh: hydraulic radius of the open channel=Wetted area of flowWetted perimeter

 

NOTE: The value of Re varies depending upon pipe flow or open channel flow. For open channel flow, the flow is typically assumed to be turbulent at Re > 12500.
