Engine oil at 100°c and a velocity of 0.05 m/s flows over both surfaces of a 0.8-m-long flat plate maintained at 20°c. determine: (a) the velocity and thermal boundary layer thicknesses at the trailing edge. (b) the local heat flux and surface shear stress at the trailing edge. (c) the total drag force and heat transfer per unit width of the plate.
