The inside diameter of an incinerator’s smokestack is 0.5 m. The flow rate of ventilation air emitted through the stack is 0.1 m3/s at 800?C. The exhaust exists the stack into an atmosphere with a 3 m/s average wind speed and an ambient temperature of 23?C at the stack exit. Determine the effective stack height for a 10-m-high smokestack given the following additional information:
a. Ground-level temperature, T = 23.2
b. Ground-level temperature, T = 23.0
c. Ground-level temperature, T = 22.0
What will be an ideal response?
a. ???????? = 23.4,????? = 11.7 ,???? = 21.7 ????
b. ???????? = 23,????? = 70.6 ,???? = 80.6 ????
c. ???????? = 22,????? = 218 ,???? = 228 ????
