Re-derive an expression for average NuL (= hLL/k) for flow over a flat plate by integrating the expression for average hL for a mixed BL. For Rex,cr, use 123456 (keeping the same sequence), and find the constant B (in Eq. 7.38). Also show that for Rex,cr = 500,000, B is indeed equal to 871.
eq. 7.38=> NuL=(0.037 ReL^(4/5)-B)Pr^(1/3)
0.6<=Pr<=60
Rex,c <= ReL <=108
