Air at 200C flowing at 25 m/s passes over a flat plate, the surface of which is maintained at 270°C. Calculate the rate at which heat is transferred from both the sides of the plate per unit width over a distance of 0.25 m from the leading edge. Properties of air at 145°C are Prandtl number = 0.687; Viscosity = 2.8 X 10-5 m2/s and thermal conductivity = 3.49 X 10-5 kW/m.K
