Glycerine having dynamic viscosity, μ = 1.5 Pa.s and density p = 1260 kg/m³ flows at a velocity of 10 m/s in a 15 cm diameter pipe. The boundary shear stress in the pipe due to the flow will be Pa.

3. At a different location in the Chesapeake, the same u-=4.4 cm/s and z,=3.1 cm were measured. At this new location, at 1 m above the bed, the Reynolds stress was measured to be u w' =-17.8 cm²/s² and the flux Richardson number was 0.23. First compute the velocity gradient at 1 meter above the bed using the logarithmic distribution and then determine the buoyancy flux ( w'p') at this location. Is the water column stably stratified?
