Challenge Problems
Push your limits with advanced challenges
A new factory is proposed to be built in an urban area. The stack’s gas velocity is expected to be 10 m/s, and the average wind speed is 5 m/s. Evaluate whether this design prevents stacktip downwash, and recommend changes if needed.
💡 Hint: Evaluate the relationship between the gas velocity and wind speed.
Discuss how a tall building positioned near a factory stack might impact local air quality. What strategies should be employed to mitigate potential negative effects?
💡 Hint: Consider the phenomenon of building downwash.
