Density. The specific gravity of gasoline is from 0.71 to 0.77, with higher densities having a greater volume of aromatics. Finished marketable gasoline is traded (in Europe) with a standard reference of 0.755 kg/L (6.30 lb/US gal), and its price is escalated or de-escalated according to its actual density.
What density of petrol is good?
The density of gasoline ranges from 0.71–0.77 kg/L (719.7 kg/m3 ; 0.026 lb/in3; 6.073 lb/US gal; 7.29 lb/imp gal), higher densities having a greater volume of aromatics. Since gasoline floats on water, water cannot generally be used to extinguish a gasoline fire unless used in a fine mist.
What is density of petrol and diesel?
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.
What is the density of water and petrol?
Density of common fluids
|Fluid||Density (g/cm3) at 20C and 1 atm unless noted|
|water (4 C)||0.99997|
|water (100 C)||0.95836|
Are diesels better than petrol?
Diesels deliver more power at lower engine revs than their petrol equivalent. This makes diesels feel more suited to longer motorway trips because they’re not working as hard as petrol engines to produce the same performance. This also helps to make diesel cars better suited for towing.
Which fuel has the highest density?
Liquid hydrocarbons (fuels such as gasoline, diesel and kerosene) are today the most dense way known to economically store and transport chemical energy at a large scale (1 kg of diesel fuel burns with the oxygen contained in ≈15 kg of air).
Which brand petrol is best for car?
Major Indian oil companies like BPCL, IOCL, HPCL guarantee a better mileage and long-run performance of the car with their premium fuel. In India unleaded petrol typically has octane ratings of 87, whereas premium fuel has an octane level of 93–94.
Which is lighter petrol or water?
petrol is lighter than water so if there is water in the fuel, it will settle to the bottom of the jar.
How much petrol is safe in a diesel car?
As a safe amount some car manufacturers will say none though the industry generally accepts 7.5% or less of petrol in diesel is safe. When you work it out for your tank capacity you will soon realise it’s not a lot of the wrong fuel before it’s too much.
How is fuel density calculated?
Experimental Density of Gasoline
Subtract the mass of the cylinder from the mass of the cylinder when it contains gasoline. This is the mass of the gasoline. Divide this figure by the volume, 100 ml, to get the density.
Is diesel heavier than petrol?
Diesel fuel is heavier than gasoline (larger molecules). Diesel fuel maintains a different density and viscosity than gasoline.
