Air at a pressure of 6 kN/m2 and a temperature of 300°C flows with a velocity of 10 m/s over a flat plate 0.5 m long. Estimate the cooling rate per unit width of the plate needed to maintain it at a surface temperature of 27°C. Kinematic viscosity of air is 5.21*10-4 m2/s, Prandtl number is 0.687 and thermal conductivity is 0.0364 W/mK.
