Air flows over a 4 meter long flat plate at a velocity of 8 m/s.Using a spreadsheet, calculate the boundary layer thickness andwall shear stress at 0.1 meter intervals along the plate. Do notplot the wall shear stress at x=0. Use a transition Reynolds numberof 5 x 10^5 . (You will need to calculate Rex at each location todetermine if the laminar or turbulent correlations should be used.)Generate a spreadsheet table that includes columns for the xlocation, Reynolds number, boundary layer thickness, and wall shearstress. Also include the exact transition location in the x column.At the transition location, calculate both the laminar andturbulent correlations and include both values in your plot. (Thesolution will have a jump at the transition point.) Plot yourresults for the boundary layer thickness and wall shear stress onseparate plots. Submit a copy of your EXCEL table and the plots yougenerated. Include a plot title and label the axes with thevariable name and units. Use only lines, no symbols, to show youranalytical solution.
