Exhaust gases from a wire processing oven are discharged into a tall stack, and the gas and stack surface temperatures at the outlet of the stack must be estimated. knowledge of the outlet gas temperature 푇",$is useful for predicting the dispersion of effluents in the thermal plume, while knowledge of the outlet stack surface temperature 푇j,$indicates whether condensation of the gas products will occur. the thin-walled cylindrical stack is 0.5m in diameter and 6.0 m high. the exhaust gas flow rate is 0.5 kg/s and the inlet temperature is 600°c. a)consider conditions for which the ambient air temperature and wind velocity are 4°c and 5 m/s respectively. approximating the thermophysical properties of thegas as those of atmospheric air, estimate the outlet gas and stack surface temperatures for the given conditions.
