Exhaust gases from a manufacturing plant are being discharged through a 10-m-tall exhaust stack with outer diameter of 1 m. The exhaust gases are discharged at a rate of 0.125 kg/s, while temperature drop between inlet and exit of the exhaust stack is 30°C, and the constant pressure-specific heat of the exhaust gases is 1600 J/kg.K. On a particular calm day, the surrounding quiescent air temperature is 33°C. Solar radiation is incident on the exhaust stack outer surface at a rate of 500 W/m2, and both the emissivity and solar absorptivity of the outer surface are 0.9. Determine the exhaust stack outer surface temperature. Assume the film temperature is 60°C.

Question
Exhaust gases from a manufacturing plant are being
discharged through a 10-m-tall exhaust stack with outer
diameter of 1 m. The exhaust gases are discharged at a rate of
0.125 kg/s, while temperature drop between inlet and exit of
the exhaust stack is 30°C, and the constant pressure-specific
heat of the exhaust gases is 1600 J/kg.K. On a particular calm day, the surrounding quiescent air temperature is 33°C. Solar
radiation is incident on the exhaust stack outer surface at a
rate of 500 W/m2, and both the emissivity and solar absorptivity
of the outer surface are 0.9. Determine the exhaust
stack outer surface temperature. Assume the film temperature
is 60°C.
