1.6-5 A cylindrical bracket that is L = 4 cm long with diameter D = 5 mm extends between a wall at T H = 100°C (at x = 0) and a wall at T C = 20°C (at x = L ). The conductivity of the bracket is k = 25 W/m 2 -K. The cylinder is surrounded by gas at T = 200°C and the heat transfer coefficient is h = 250 W/m 2 -K. a.) Is an extended surface approximation appropriate for this problem? Justify your answer. b.) Assume that your answer to (a) was yes.

Unformatted text preview: Develop an analytical model in EES. Plot the temperature as a function of position within the bracket. c.) Overlay on your plot from (b) the temperature as a function of position with h = 2.5, 25 and h = 2500 W/m 2-K. Explain the shape of your plots. d.) Plot the heat transfer from the wall at T H into the bracket (i.e., the heat transfer into the bracket at x = 0) as a function of h . Explain the shape of your plot....
