Thermal Conductivity Problems: a. A wall is made of firebrick 6 inches thick and has a 50°C difference in temperature both sides. Calculate the heat transferred through the wall if the thermal conductivity of the brick is 0.65 BTU/hr-ft- oF. b. Compute the amount of heat flow per second through an iron plate 2 cm thick and the area of 5000 cm² if one face has a temperature of 150°C and the other face is 140°C? The thermal conductivity for iron is 80 W/m-K.
