Calculate the rate of heat loss per cm² through a stabilized zirconia (ZrO₂) lining of a high-temperature laboratory furnace operated at 1,400 degrees Celsius. The external face of the lining is at 100 degrees Celsius, and its thickness is 1 cm. Assume the data for stabilized zirconia in Table 7.4 are linear with temperature and can be If needed, extrapolated to 1,400 degrees Celsius. use the information on the following page.
