Part A Atypical SHOW i9'°° (thermal oonductivity‘about 1’10 9f be) is shaped What is the conductive heating rate through the walls if the inside temperature is 12 °C and the outside temperature is .17 °C ’?
like a hemisphere of Inner radius 1.5 in With 0.36m: thick walls. Hint: Use the conductive heating equation HConduiction = KA(T§ 7 T1)/l, where A is surhoe area, I is the distance that the thermal energy travels. and K is thermal conductivity. To calculate the surface area use the
mean radius ofthe wall that is an average of inner and outer radii. Express your answer to two significant figures and Include the appropriate units. HConduction = 2528 W m My Answers Give Up Incorrect; Try Agaln, Dmuidn Endhanll m
