A family is preparing dinner and a pizza is being toasted in an oven whose wall is ma a 0.5-cm-thick layer of steel (ks = 15 W/m·K) and a layer of brick (kb = 0.72 W/m.k steady state, the oven inner surface temperature of the steel layer is 450°F, a temperature drop of 0.5°C occurs across the steel layer. If the temperature of the surface of the brick must be no greater than 40°C for safety concerns, determine thickness of brick in cm, that ensures this limit is met. What is the rate of conduction called boat flund in /(m²?

Question
A. A family is preparing dinner and a pizza is being toasted in an oven whose wall is made of a 0.5-cm-thick layer of steel (ks = 15 W/m.K) and a layer of brick (kb = 0.72 W/m.K). At steady state, the oven inner surface temperature of the steel layer is 450°F, and a temperature drop of 0.5°C occurs across the steel layer. If the temperature of the outer surface of the brick must be no greater than 40°C for safety concerns, determine the thickness of brick in cm, that ensures this limit is met. What is the rate of conduction per unit wall surface area (also called heat flux), in kW/m²?
