A spherical furnace has an inside diameter of 6ft and an outside diameter of 8ft. The furnace shell is made of two different materials, each 6inches thick. The inner and outer section of the shell has a thermal conductivity of 0.10 BTU/hr-ft- °F and 0.2 BTU/hr-ft- °F, respectively. The inside temperature is 2, 500 °F, while the outside surface is at 150°F. Calculate the heat loss for 24 hours of operation. Express your answer in scientific notation. 1= 3ft r2= 4ft r3= 4.5ft r2= 5ft A= inner section B= outer section KA= 0.1 BTU/hr-ft- °F kB= 0.2 BTU/hr-ft- °F T1= 2500 °F T4= 150 °F
