A wall is composed of two materials, material 1 has a thickness of 3.68 cm and a thermal conductivity of 0.1 J/msCo while material two has a thickness of 6.02 cm and a conductivity of 1 J/msCo, if the temperature difference inside to outside is 25 Co and the wall has an area of 10 m2, what is the energy loss per second to the nearest watt?
In the previous problem, if the inside temperature is 29.6 oC, what is the temperature of the interface to the nearest degree celsius?
