Question: A wall with a height, width and thickness of 60 cm, 45 cm, and 1.25 cm respectively is made of a material with a thermal

A wall with a height, width and thickness of 60 cm, 45 cm, and 1.25 cm respectively is made of a material with a thermal conductivity value as a function of temperature, k(T) = 0.0013T+0.012 W/m.K. One side of the wall surface is in contact with air with a temperature of 75 degrees C and the other side is in an air environment with room temperature (about 25 degrees C). a. Sketch the system above! (also include a temperature gradient sketch) b. Determine the assumptions needed to calculate the rate of heat transfer on the wall! c. Calculate the rate of heat that moves through the dividing wall! d. How would you calculate the overall heat transfer of the wall system? Is the data provided sufficient? If not, what data are needed to calculate the overall heat transfer of the wall system above?
