2. Solve the laminar boundary layer for constant free-stream velocity, using the momentum integral equation and an assumption that the velocity profile may be approximated by ±-0-0 Исо for an isothermal surface using a quadratic temperature profile with a function of thermal layer thickness, A, is (T-T)/(T-T)=1-2(y/A)+(y/A)². Evaluate the momentum thickness (6), displacement thickness 62, and friction coefficient C, and the Nusselt number.
