Hello! Today we are going to know the density of diesel. Diesel is a combustible liquid used as fuel for diesel engines, ordinarily obtained from fractions of crude oil that are less volatile than the fractions used in gasoline. In diesel engines, the fuel is ignited not by a spray, as in gasoline engines, but by the heat of air compressed in the cylinder, with the field injected in a spray into the hot compressed air. Do you know? Diesel releases more energy on the combustion that equals volumes of gasoline, so diesel engines generally produce better fuel economy than gasoline engines. So, without wasting your valuable time let’s know about the density of diesel.

**What Is The Density Of Diesel?**

The density of diesel is about 0.85 kg/l. It is about 15 to 20% higher than the density of gasoline which has a density of approximately 0.70 to 0.75 kg/l. When diesel gets burnt then it releases energy that is nearly equal to the extent of 37.7 to 39.1 MJ/l. whereas gasoline releases approximately 34.9 MJ/l. the diesel density increases in cold-weather regions making the diesel become thicker like in the form of a gel which will reduce its viscosity thus preventing its flow into the fuel systems. Therefore, special additives have to be used to keep it in a liquid state. Diesel density in other units as,

The density of diesel in g/cm3 is 0.9 g/cm, the density of diesel fuel lb/gal is 7.09 lb/gal, while the density of diesel lb/ft3 is 54.6 lb/ft3. Similarly, the density of diesel in g/ml is between 0.825 to 0.850 g/ml, the density of diesel kg/m3 is 875 kg/m3, and the density of diesel in kg/l is 0.85 kg/l.

Now, you know about the diesel density in all units. Let me tell you the definition of diesel density in detail.

**Definition Of Density Of Diesel**

The density of diesel is the ratio of the mass of diesel to the volume of diesel. The diesel density is dependent on the temperature and you get more diesel when the temperature is high. It is because the diesel becomes more liquid when it comes in contact with sunlight. You can represent this definition in the form of its symbols such as,

The density of diesel = mass of diesel/volume of diesel g/ml

⍴ = m v g/ml

Where, m is the mass of diesel

v is the volume of diesel, and

⍴ is the density of diesel.

Let me tell you about how to calculate the diesel density with the help of an example.

**How To Calculate Density Of Diesel?**

So, to calculate the density of diesel just follow the steps given below.

- First of all, measure the mass and volume of the given diesel.
- To measure the volume and mass of diesel, take an empty container of a fixed known volume.
- Measure the weight of the empty container. Not down it.
- Fill the empty container totally with diesel and measure its weight again.
- Subtract the weight of the container from the total weight, and you will get the actual weight of diesel.
- Now you know the mass of diesel and volume you know already.
- Just divide the mass by volume and you will get the density of diesel.

Now, let’s understand with the help of an example.

A cylindrical container of 50 m3 volume and it is filled with 100 kgs of diesel, then find the density of diesel.

So, use the above given formula

The density of diesel = mass of diesel/volume of diesel

= 100/ 50 = 2 kg/m3

So, the density of diesel is 2 kg/m3 .

**FAQ**

**What Is Diesel Density Kg M3?**

Issued: July 2018. Density at 15 °C = 840 kg/m^{3}

**How Do You Calculate Diesel Density?**

For example, if you poured 16 ml of fluid in the cylinder, you will use 16 ml. If the total weight of the fluid is 16 grams, the calculation would be 16 g / 16 ml. This would give you a density of 1 g/ml.

**Which Has Higher Density Petrol Or Diesel?**

However, diesel fuel is denser than petrol and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre).

**What Is The Best Diesel Density?**

The density of petroleum diesel is about 0.85 kg/l – about 15–20% higher than the density of gasoline, which has a density of approximately 0.70–0.75 kg/l.

**Is Diesel Denser Than Water?**

Water is denser than diesel, so if it is present then it will sink to the bottom of the container.

**Is Diesel More Dense Than Gasoline?**

Diesel and petrol engines

However, **diesel fuel is denser than petrol** and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre).

**Is Diesel More Dense When Cold?**

Because diesel and gasoline are fluids, **they become much denser when it is cold**.

**Conclusion**

While reading this article you became well aware of the diesel density as well as its calculation. Energy density is 0a great method of measuring energy capacity not only for diesel fuel, but alternative fuels as well. By definition, energy density is the amount of energy stored in a given system or region of space per unit volume or mass. The energy density for diesel fields ranges from 32 to 40 MJ/L, as we already told you. Now, you will never forget about the density of diesel in the future.
