Problem 1 A 75-cm-thick wall (k = 30 W/m-K) is exposed to convection on one side. The air is at 30 °C and has a heat transfer coefficient of 100 W/m2-K. On the side not exposed to convection, the wall is at 20 °C. The surface area is 10 m2. Using a thermal resistance network, determine the rate of heat transfer passing through the wall in Watts
