(a) Using the integral method with profile (3) of Table 9.2, determine the boundary-layer thickness for planar stagnation flow, where u(x) = ax.

(b) With the wall shear stress written as

a numerical solution of the Falkner–Skan equation for planar stagnation flow gives K = 1.233 (Jones and Watson, 1963, p. 232). How does your approximate value compare with this?
