## Specific Energy Formula

The following equation is used to calculate the Specific Energy.

SE = E / m

Variables:

- Where SE is the Specific Energy (J/kg)
- E is the total energy (J)
- m is the total mass (kg)

To calculate the specific energy, divide the total energy by the total mass.

## How to Calculate Specific Energy?

The following two example problems outline the steps and information needed in order to calculate the Specific Energy.

**Example Problem #1:**

- First, determine the total energy (J). In this example, the total energy (J) is measured to be 6.
- Next, determine the total mass (kg). For this problem, the total mass (kg) is calculated to be 8.
- Finally, calculate the Specific Energy using the formula above:

SE = E / m

Inserting the values from above and solving the equation with the imputed values gives:

SE = 6 / 8 = .75 (J/kg)

**Example Problem #2: **

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:

total energy (J) = 4

total mass (kg) = 3

Entering these values into the formula or calculator above gives us: SE = 4 / 3 = 1.33** **(J/kg)
