4-1. Repeat the momentum-integral analysis of the flat plate in Sec. 4-1 for Pohlhausen's cubic polynomial profile =3() - () [Pohlhausen (1921)] where 8(x) is the boundary-layer or disturbance thickness as pictured in Fig. P4-1. Is this profile any more (or less) realis- tic than the approximation of Eq. (4-11)? For the above profile, compute (a) (0/x)/Re; (b) (6*/x)/Re; (c) (8/x)/Re; (d) CRe: (e) C Rex. Answers: (a) 0.646, (b) 1.740, (c) 4.64, (d) 0.646, (e) 1.293 8(x) FIGURE P4-1
