For the situation described in Example 6.4, the bound-ary
Chapter 6, Problem 6.23(choose chapter or problem)
For the situation described in Example 6.4, the bound-ary layer can be trippedinto a turbulent state byapplying roughness to the surface of the flat plate at aparticular x-location. Hence the location where transi-tion occurs, xc, can be moved upstream relative to thetransition location associated with the smooth plate ofthe example. Calculate and plot the average convectioncoefficient over the entire plate for roughness appliedover the range 0?xr?L. What values of xrprovidethe minimum and maximum values of ? Assume thewater temperature is 300 K
