During air cooling of a flat plate (k = 1.4 W/m ∙ K), the convection heat transfer coefficient is given as a function of air velocity to be h 5 27V 0.85, where h and V are in W/m² ∙ K and m/s, respectively. At a given moment, the surface temperature of the plate is 75°C and the air (k = 0.266 W/m ∙ K) temperature is 5°C. Using EES (or other) software, determine the effect of the air velocity (V) on the air temperature gradient at the plate surface. By varying the air velocity from 0 to 1.2 m/s with increments of 0.1 m/s, plot the air temperature gradient at the plate surface as a function of air velocity.
