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:

- First, determine the maximum capacity of the operation (units/hr).
- The maximum capacity of the operation (units/hr) is given as: 3,000.

- Next, determine the emission factor.
- The emission factor is provided as: .50.

- 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** = ?**
