Using the continuity equation u/ x + v/ y=0 along with the velocity distribution

Question

Using the continuity equation u/ x + v/ y=0 along with the velocity distribution u/u infinity =3/2 y/delta - 1/2(y/delta)3 and and the expression for the boundary-layer thickness delta/x=4. 64/ Rex derive an expression for the y component of the velocity, v, as a function of x and y. Calculate the value of v at the outer edge of the boundary layer (y=delta) at distances of x=15 and 30 cm from the leading edge for air at 27C, P=1 atm, u delta=2 m/s. the dynamic viscosity of air, mu = 1.85 times 10-5 Kg/ms, density rho=0.99 kg/m3.
