A liquid flows over a flat naphthalene plate of length L. at a Reynolds number (ReL=Lρu∞/μ) of 1500. as shown in the figure. The surface concentration of naphthalene is CA,s>CA,∞ and the surface temperature is Ts>T∞. Assume Pr=Sc=1.
If, at x=L, ∂CA*/∂y*|y*=0=10. where CA*=(CA-CA,∞)/(CA,s-CA,∞) and y*=y/L, then the Nusselt number and the friction coefficient at x=L, are
