1.1. Emission Rate and Factors

Try these first

1. 1.

   Define emission rate in your own words.

   Hint

   Think about what it measures in terms of time and pollutants.

2. 2.

   What is an emission factor?

   Hint

   Relate it to the activities you observe daily.

3. 3.

   What two components are used to determine the emission rate?

   • Emission Factor and Activity Rate
   • Temperature and Pressure
   • Pollutants and Sources

   Hint

   Refer back to the formula discussed in class.

4. 4.

   True or False: Fugitive emissions are planned and controlled.

   • True
   • False

   Hint

   Think about the definition we covered in class.

5. 5.

   Calculate the total emissions from a city that has 500 vehicles, where each vehicle emits an average of 250 grams of CO2 per kilometer and drives 15 kilometers per day.

   Hint

   Break it down into three parts: vehicles, emissions per vehicle, and how far they travel.

6. 6.

   A power plant emits 30 tons of NOx per day when burning coal. If the emission factor is 1.5 kg of NOx per ton of coal, how many tons of coal does it burn daily?

   Hint

   Convert tons to kilograms if needed and rearrange the equation.
