Air with a temperature of 20°C is flowing over a flat plate (k = 15 W/m · K) at a velocity of 3 m/s. The plate surface temperature is maintained at 60°C. Using EES (or other) software, determine the effect of the location along the plate (x) on the heat transfer coefficient and the surface temperature gradient of the plate. By varying x for 0 < x ≤ 0.5 m, plot the heat transfer coefficient and the surface temperature gradient of the plate as a function of x. Evaluate the air properties at 40°C and 1 atm.
