Hot exhaust gases are discharged from a plant into the atmosphere through a 0.7 mdiameter vertical stack that is 9 m high. Gases enter the stack at 5 m/s, 502oC, and approximatelyatmospheric pressure. They can be assumed to behave as air. Wind blows over the outside of thestack, resulting in an exterior heat transfer coefficient of 17 W/m2-K. Find the interior heattransfer coefficient. Is heat transfer best on the interior or exterior surface of the stack? Explainyour answer.
