Question:

The upper surface of a metal plate is being cooled with parallel air flow while its lower surface is subjected to a uniform heat flux of 810 W/m2. The air has a free stream velocity and temperature of 2.5 m/s and 15°C, respectively. Determine the surface temperature of the plate at x = 1.5 m from the leading edge.
