Parallel flow of air over a flat plate of length 3m is disrupted by an array of stationary rods placed in the flow path over the plate. an empirical correlation for the local heat transfer coefficient is obtained for a velocity, v and ts> [infinity]t: hx=0.7+13.6x-3.4x2, where hx has units of w/(m2*k) and x is in meters. evaluate the average heat transfer coefficient for the entire plate and the ratio llh/h at the trailing edge. also plot the heat transfer coefficient as a function of x (from x=0 to x=3m). how does this plot compare to flow over a flat plate without any stationary rods?
