Question 1.
What is the definition of emission rate?
Show hintHide hint
Think about how emissions are measured.
Question 2.
What does wind speed at stack height inform us?
Show hintHide hint
Consider its role in pollution models.
3Question 3.
What is the primary reason to measure wind speed at the stack height?
- To calculate pollutant concentration
- To determine temperature
- To find emission rate
Show hintHide hint
Consider how pollutants behave in relation to wind.
4Question 4.
True or False: Windrose diagrams represent wind direction 'to' various locations.
- True
- False
Show hintHide hint
Think about how winds are typically reported.
Question 5.
A factory emits 200 kg of CO2 per hour, and the emission factor is 0.8 kg/kg of coal burned. If the daily burn rate of coal is 1 ton, calculate the total CO2 emissions for a week.
Show hintHide hint
Consider both hourly and daily rates.
Question 6.
If the wind speed at stack height is calculated using a power law and determined to be 12 m/s, but the measurement at the anemometer is taken at 30 m high where it was 10 m/s, discuss adjustments that might be needed.
