2.4.2. Coning Plume Shape

Try these first

1. 1.

   What is a coning plume shape?

   Hint

   Think about the shape it creates in the air.

2. 2.

   Name one factor that affects plume shape.

   Hint

   Consider what atmospheric conditions lead to strong winds.

3. 3.

   Which plume shape is characteristic of neutral atmospheric conditions?

   • Looping
   • Coning
   • Fanning

   Hint

   Think about what remains constant in neutral conditions.

4. 4.

   True or False: Turbulence can create looping plume shapes.

   • True
   • False

   Hint

   Recall what looping indicates about air movement.

5. 5.

   Given an environmental lapse rate of -6°C/km and an adiabatic lapse rate of -9.8°C/km, determine the possible mixing height for a pollutant release. Explain the conditions of stability.

   Hint

   What happens when environmental conditions exceed adiabatic conditions?

6. 6.

   Analyze a situation where a factory operates at a temperature of 200°C. Discuss the implications for plume shape and dispersion under varying environmental conditions.

   Hint

   How does temperature influence buoyancy in different atmospheric scenarios?
