Problem 1: A furnace has a 4 m high composite wall constructed of 4 cm thick fireclay brick on the inside, and 10 cm of oval-core concrete block with sand in the cores as the outer surface. The inside surface of the wall is at 400°C. The outer surface is exposed to quiescent air at 23°C (i.e., natural convection is occurring). What is the steady-state temperature of the outer surface of the wall? Use a film temperature of 400K to...

A flat composite wall consists of four layers of different materials (Concrete, Carbon steel, Kapok, and Masonry Brick). Each layer is 4 inch thick. During service, heat energy transfers from the left side of the wall (higher temperature-500°C) to the right (lower temperature 20°C), thus generting the temperature profile as shown in figure below. Please identify material for each layer and provide explanation (or short calculations if applicable). Also, determine temperature at the boundary between A.1 3d and 4th layers....
