Reconsider Prob. 7–55. Using the EES (or other) software, evaluate the local convection heat transfer coefficient, the local surface temperature, and the local film temperature along the plate. By varying the location along the plate for 0.2 ≤ x ≤ 3 m, plot the local convection heat transfer coefficient, the local surface temperature, and the local film temperature as function of x.

Data from problem 55

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. The surface temperature has to be found iteratively. Start the iteration process with an initial guess of 45°C for the surface temperature.
