1. Find the overall resistance per metre length for the following: αi = 1000 W/m2K, αo = 300 W/m2K, 1¼ in. standard type M copper tube, λcopper = 399 W/mK. Make the calculations assuming no wall resistance, then again assuming wall resistance, compare the results. (Refer to the wall resistance equation through a cylinder from Heat Transfer)

Assume that we are working with an aluminum alloy (k = 180 W/moC) triangular fin with a length, L = 5 cm, base thickness, b = 1 cm, a very large width, w = 1 m. The base of the fin is maintained at a temperature of T0 = 200oC (at the left boundary node). The fin is losing heat to the surrounding air/medium at T? = 25oC with a heat transfer coefficient of h = 15 W/m2oC. Using the...
