2.3. Petroleum diesel has a density of about 0.85 kg/l, which is about 1520 percent greater than gasoline, which has a density of about 0.700.75 kg/l.
What is the fuel’s specific gravity?
Fuels can have a wide range of qualities. Octane, oxygen, lead content, and something called specific gravity, which assesses a substance’s density in comparison to a standard, are the biggies. Water is the standard when the substance is a liquid. Because gasoline is lighter than water, most mixes have a specific gravity of 0.7 to 0.8. Even if you don’t choose a fuel based on its specific gravity, that value might tell you a lot.
What is #2 diesel fuel’s specific gravity?
The API gravity of No. 2 diesel fuel is between 30 and 42 at 60 degrees Fahrenheit (15.6 degrees Celsius). At 60/60F, the specific gravity is 0.88, and the density is 0.82 at 15.6C.
How much does a liter of diesel weigh?
When one litre of petrol is burned, it creates approximately 2.31 kg of carbon dioxide. A litre of diesel, which weighs roughly 840g, emits an additional 2.68kg of CO2. CO2 is a strong greenhouse gas that is produced during the combustion process in your engine.
Your fuel economy is linked to the quantity of CO2 you emit when driving. The more fuel you consume per km, the more carbon dioxide you produce per kilometre, and car manufacturers frequently provide this statistic. For example, a Ford Ranger with a combined fuel economy of 8.3-8.8 litres per 100km produces between 218 and 230g/km.
We must look at the chemistry to understand why the total carbon dioxide created is heavier than the starting litre of fuel: Although diesel and gasoline are high in carbon, carbon is rather light. When the fuel is burned, the carbon joins with two oxygen molecules (both heavier than the carbon) to form carbon dioxide. Each oxygen molecule is approximately 25% heavier than a carbon molecule, and there are two of them!
To put it in numerical terms, one molecule of carbon weighs 12 grams, while two molecules of oxygen weigh 32 kg!
But what percentage of diesel and gasoline is carbon? About 720g of the 840g that one litre of fuel weighs is carbon. Around 640g of the 740g that one litre of petrol weighs is carbon.
What is water’s specific gravity?
Specific gravity, abbreviated as sp gr, is the ratio of a solid’s or liquid’s density to the density of water at 4 degrees Celsius. The word can also refer to the ratio of a gas’s density to that of dry air at standard temperature and pressure, however this is a less common specification. Specific gravity is a dimensionless quantity, meaning it does not have a unit of measurement.
You must know the density of a solid or liquid in kilograms per meter cubed (kg/m3) or grams per centimeter cubed (g/cm3) to calculate the sp gr. Then, in the same units, divide this density by the density of pure water. Divide by 1000 if you’re using kg/m3. Divide by 1 if you’re using g/cm3 (that is, leave the number alone). It is critical that the numerator and denominator utilize the same units.
The specific gravity of water is one. Materials with a specific gravity less than one are less dense than water and will float; substances with a specific gravity greater than one are more dense than water and will sink. Having a specific gravity of 0.085, an object with a density of 85 kg/m3 will float high on the surface of a body of water. With a specific gravity of 85, an object with a density of 85 g/cm3 will sink quickly.
To determine a gas’s specific gravity, you must first determine its density in kilograms per meter cubed (kg/m3). The density of dry air at standard temperature and pressure is then divided by this density. This figure is roughly 1.29 kg/m3. Gases having a specific gravity of less than one will ascend in the atmosphere at sea level, while gases with a specific gravity of greater than one will sink and seek low-elevation areas on the earth’s surface.

Which of the following fuels has the highest specific gravity?
The higher the C/H ratio, the heavier (higher specific gravity) the crude oil. The greatest heating value is 5.4 MJ/kg for paraffins, while the lowest is 5.4 MJ/kg for aromatics. Propane has a higher heating value of 42.4 MJ/kg than benzene, with a difference of 0.8 kJ/kg (Table 2).
Is it true that diesel floats on water?
Anyone who works with diesel fuel, from builders and landscapers to delivery companies and auto dealerships, is aware that water issues are a constant concern. Whether you preserve it for a long time or not, this is the situation. You’re in big trouble if water gets into your diesel fuel system. Contamination of water wreaks havoc on this powerplant. Let’s take a look at the primary reasons why water and diesel don’t mix.
We all know that water freezes. However, did you know that it freezes faster than gasoline? Here’s an example of a comparison:
- The temperature of the water is 32 degrees Fahrenheit.
- -20 degrees Fahrenheit for fuel
When water gets into your gasoline, it freezes, resulting in issues such as power loss, clogged filters, corrosion of fuel parts, and injector damage. That’s why, if there’s water, you’ll notice greater problems in the winter.
Gas is more refined than diesel, so while having water in your gas tank is bad, it’s even worse with diesel because it hangs onto more water. In addition to the issues listed above, your engine’s lifespan may be shortened, and repairs may be costly. If you need to repair a fuel injector because it exploded, for example, it will be expensive.
Diesel and water, like oil and water, do not mix; they separate. As a result, if you have water in your tank, it will settle to the bottom. Your tank will rust and algae will bloom as a result of that water. Rust floats about in your fuel filters, obstructing and ruining them. Bacteria create waste and continue to eat away at the engine and its components.
It’s not uncommon for condensation to form and then dissipate as the temperature outside changes. That isn’t the issue. It occurs when there is an excessive concentration of water. When this happens, problems like engine power loss arise. Look at the fuel; if it’s clear, that’s a good sign. There’s a problem if it isn’t, for example, if it’s cloudy. That is why routine maintenance is critical.
There’s a good likelihood you have water difficulties if you notice your vehicle or equipment isn’t performing well, especially if the idling is inconsistent. If the engine cuts off during acceleration, there are two alternative ways to tell.
Microbes multiply quickly in your tank, produce waste, and are difficult to eradicate. This is especially true if the underlying water problem isn’t addressed, as bacteria and fungus require water to survive.
A gasoline additive might work if there isn’t much water in the tank. Otherwise, the tank will have to be drained. If you have an above-ground tank, this is the best and most complete option. After that, clean the inside and remove any rust or corrosion. If you haven’t done this in a long time, your tank may need to be fixed or replaced. Ricochet Fuel can assist you.

What does diesel’s viscosity mean?
2 At 40C, diesel fuel has a viscosity of 2.53.2 cSt, while biodiesel made from the methyl esters of soybean oil has a viscosity of 4.24.6 cSt (1,36).
How can you know if a diesel is good?
In our country, diesel fuel is used in the majority of heavy-duty commercial vehicles. Every month, fleet owners spend thousands of rupees on premium fuel to keep their buses and trucks running smoothly. You can do a simple test to ensure that the diesel in your vehicle is of good grade. You’ll need a 500-millilitre glass jar, a thermometer, a hydrometer, and an ASTM (American Society for Testing of Materials) conversion chart to complete this check.
This experiment’s hydrometer is used to determine the density of any liquid (in this case, diesel). You can get this device at the gas stations if you ask for it. Fill the jar 3/4 full with diesel. Place the thermometer and hydrometer within the oil and measure the temperature. The figure acquired in the equipment must then be compared to the expected value. If the difference is greater than +/-3.0, you can file a complaint with the appropriate higher authority.
If you can’t find a hydrometer or a thermometer, we have another simple test for determining the purity of fuel. The nicest part about this experiment is that it just takes around twenty minutes to complete. This test is based on the fact that diesel oxidizes after sitting in a tank for more than a month. Only a test vial, a sampling pipette, and an oxidation catalyst are required. In the vial, pipette out 10 milliliters of diesel and add the oxidation catalyst. It will turn dark in twenty minutes if the fuel is old. It’s worth noting that oxidized diesel causes sludge in tanks and filter blockage.
You can examine the quality of petrol in the same way that you can check the quality of diesel. This analysis just necessitates the use of filter paper. First, properly clean your vehicle’s nozzle to ensure there are no dirt residues. Apply a drop of petrol to the filter paper with the nozzle. Gasoline should ideally evaporate in two minutes without leaving a stain on the paper. Dark pigment on the filter paper indicates that the gasoline has been tampered with. For further action on the petrol pump where you purchased the fuel, contact the Consumer Protection Department.
What is the formula for calculating diesel density?
If you poured 16 ml of fluid into the cylinder, for example, you will utilize 16 ml. The computation would be 16 g / 16 ml if the total weight of the fluid is 16 grams. You’ll have a density of 1 g/ml if you do this. Carefully and properly dispose of the fuel from the cylinder.
