Specific energy is a term that carries significant weight in numerous disciplines, such as physics, chemistry, and engineering. In essence, it is the energy per unit mass. This measure proves useful when comparing different substances or materials based on their energy storage capacity. In this article, we’ll introduce the workings of a specific energy calculator, the underlying formula it uses, and provide an illustrative example.

What is Specific Energy?

Specific energy is a metric that represents the energy per unit mass. Its standard SI unit is Joule per kilogram (J/kg). Essentially, it demonstrates how much energy a particular quantity of a substance or material holds. A higher specific energy value indicates that the substance can store more energy per unit of its mass.

The Formula Behind Specific Energy Calculation

The formula to calculate specific energy (E) is quite straightforward:

E = e / m

In this formula:

  • E stands for the specific energy,
  • e is the total energy, and
  • m refers to the mass of the substance or material.

The Functioning of a Specific Energy Calculator

A specific energy calculator operates on the formula outlined above. To use it, you need to input two key variables: the total energy and the mass of the substance. Here’s how it works:

  1. Input the total energy (e) in Joules.
  2. Input the mass (m) in Kilograms.
  3. Hit the calculate button.

The calculator will then divide the total energy by the mass to provide the specific energy in Joules/Kilogram. It’s worth noting that most calculators also offer a reset button to clear all the fields for a fresh calculation.

An Example of Specific Energy Calculation

To better understand how specific energy is calculated, let’s look at an example.

Suppose we have a battery with a total energy storage capacity of 1000 Joules and a mass of 2 kilograms. To find out its specific energy, we input the total energy and mass into our calculator.

After hitting the ‘Calculate’ button, the calculator applies the formula, dividing the total energy (1000 Joules) by the mass (2 kilograms). The resulting specific energy is 500 Joules/Kilogram, meaning for every kilogram of the battery, it can store 500 Joules of energy.

This shows that the battery has a relatively high specific energy and thus a high energy storage capacity for its size.
