In flow over a surface, velocity and temperature profiles are of the forms u(y) = A y +By-Cy T(y) = D+Ey+ Fy-Gy where the coefficients A through G are constants. a) Obtain expressions for the friction coefficient C; and the convection coefficient h in terms of uz, T, and appropriate profile coefficients and fluid properties. b) If the mentioned surface is a flat plate, and the variation of the coefficients with the distance along the plate are -0.2 C& (x) = K, x h (x) = K, x04 compare the local and average coefficients for a plate of length L.
