Enter the maximum capacity of the operation (units/hr) and the emission factor into the Emission Rate Calculator. The calculator will evaluate the Emission Rate. 

Emission Rate Formula

The following two example problems outline the steps and information needed to calculate the Emission Rate.

ER = C * EF

  • Where ER is the Emission Rate (units/hour)
  • C is the maximum capacity of the operation (units/hr) 
  • EF is the emission factor 

How to Calculate Emission Rate?

The following example problems outline how to calculate Emission Rate.

Example Problem #1:

  1. First, determine the maximum capacity of the operation (units/hr). 
    • The maximum capacity of the operation (units/hr) is given as: 3,000.
  2. Next, determine the emission factor. 
    • The emission factor is provided as: .50.
  3. Finally, calculate the Emission Rate using the equation above: 

ER = C * EF

The values provided above are inserted into the equation below and computed.

ER = 3000 * .50 = 1,500 (units/hour)


Example Problem #2: 

For this problem, the variables required are provided below:

maximum capacity of the operation (units/hr) = 6,000

emission factor = .10

Test your knowledge using the equation and check your answer with the calculator..

ER = C * EF = ?
