Air at 1 atm and 20 deg C is flowing over the top surface of a 0.2 m X 0.5 m-long metal foil. The air stream velocity is 100 m/s and the metal foil is heated electronically with a uniform heat flux of 6100 W/m^2. If the friction force on the metal foil surface is 0.3 N, determine the surface temperature of the metal foil. Evaluate the fluid properties at 100 deg C.
