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?
