Specific Weight of Diesel Fuel, Its Density and Value Table
Diesel fuel, also commonly called solyarka in Russian, is a liquid product used as fuel in diesel internal combustion engines. This material is obtained from gas oil and kerosene fractions during direct oil distillation.
This product is intended for use as fuel in diesel engines operating in the range of 600 to 1000 revolutions per minute. The main consumers of diesel fuel are freight road transport, railway transport, military equipment, water transport, agricultural machinery, diesel generators, and some types of light vehicles.
In colloquial speech, this material received the name "solyarka" from the German word Solaröl, which means "solar oil". This term was used for heavy fractions obtained during oil distillation.
When working with diesel fuel, it is important to take its quality into account. This can partly be assessed by such a parameter as the specific weight of diesel fuel.
Diesel Fuel Specific Weight Table
Since diesel fuel is a complex substance, it is not possible to calculate its specific weight independently in field conditions. These calculations are made using a special device called a hydrometer. However, the average specific weight is known and corresponds to the values shown below in the table, which helps simplify calculations and determine such a parameter as the weight of diesel fuel.
| Material | Specific weight (g/cm3) | Weight of 1 m3 (kg) |
| Summer diesel fuel | 0,86 | 860 |
| Winter diesel fuel | 0,84 | 840 |
Specific Weight Calculations
To calculate specific weight, it is necessary to define what this concept means. Specific weight is the ratio of the weight of the substance under consideration to its volume. It is expressed by the formula: y=p*g, where y is specific weight, p is density, and g is gravitational acceleration, which under normal conditions is a constant equal to 9,81 m/s*s.
The results are usually measured in Newtons divided by cubic meter and denoted as N/m3.
Diesel Fuel Density
The density of any substance is the amount of its mass in kilograms that fits into one cubic meter. This is a variable value that depends on many factors. The main one is temperature. The higher the temperature of diesel fuel, the lower its density. In practice, this means that diesel fuel with unsuitable density negatively affects the operation of a diesel engine.
Frequently Asked Questions
Can the density of diesel fuel be used for precise calculations?
The density and weight values for diesel fuel in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of diesel fuel differ from the table?
The actual weight of diesel fuel depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of diesel fuel from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of diesel fuel is given in kg/m³ and the volume is in m³, the result will be in kilograms.
