Question 1

What is the primary concern of building downwash?

  • It reduces stack height
  • It causes pollutants to accumulate
  • It increases stack velocity

💡 Hint: Focus on the impact of building shapes on airflow.

Question 2

True or False: A stack's gas velocity should be less than the wind speed to ensure proper dispersion.

  • True
  • False

💡 Hint: Remember the required velocity mentioned in class.

Challenge Problems

Push your limits with challenges.

Question 1

A city building has a stack that releases pollutants at a height of 10 meters. If the building is 8 meters tall, calculate if the current stack height is sufficient under average wind conditions of 2 m/s. Determine if the stack velocity meets standards.

💡 Hint: Check if the stack reaches high enough and if the velocity is adequate.

Question 2

Assess how modifications to relief vents on a building can improve overall air quality. Consider the effects of building downwash in your solution.

💡 Hint: Think of how airflow needs to move through and around buildings.
