Question

Please don’t copy from another answer I need clear solution

2-15. To illustrate ..boundary-layer" behavior, i.e., the effect of the no-slip condition for large Reynolds numbers, Prandtl in a 1932 lecture proposed the following model (lin- ear) differential equation: du du dy where e mimics the smal viscosity of the fluid. The boundary conditions are (1) u(0) 2, and (2) u remains bounded as y becomes large. Solve this equation for these conditions and plot the profile u(y) in the range 0 < y < 2 for E-0, 0.01, and 0.1. Comment on the results. Is the plot for e0 the same as that obtained by setting e0 in the original differential equation and then solving?
