What is the shape of petrol?
Hint: The petrol tank is in the shape of a cylinder with two hemispheres of same radii attached to the both sides.
What are the characteristics of fuel oil?
Fuel oils are yellowish to light brown liquid mixtures produced from crude petroleum by different refining processes, depending on their intended use. They generally have a kerosene-like odor and are flammable.
What does heavy fuel oil look like?
In contrast to HFOs, distillates are the petroleum products created through refining crude oil and include diesel, kerosene, naptha and gas….Heavy fuel oil use and shipping.
| Category of Marine HFO | Marine HFO Composition |
|---|---|
| Intermediate Fuel Oil (IFO) 380 | distillate combined with 98% residual oil |
What type of fuel is oil?
The term fuel oil generally includes any liquid fuel that is burned in a furnace or boiler to generate heat, or used in an engine to generate power. However, it doesn’t usually include other liquid oils, such as those with a flash point of approximately 42 °C (108 °F), or oils burned in cotton- or wool-wick burners.
Why are oil containers round in shape?
Interview Answer. Gas bottles are cylindrical or spherical because circular hoops can withstand internal pressure by pure tension in the tank material instead of bending. Materials can take more force in tension than in bending.
What is the viscosity of fuel oil?
Figure 1
| property | test method | heavy fuel oil |
|---|---|---|
| sulfur content (mass %) | ASTM D2622 | 0.656 |
| pour point (°C) | ASTM D5950 | 6 |
| viscosity at 50 °C (cSt) | ASTM D445 | 731.94 |
| viscosity at 100 °C (cSt) | ASTM D445 | 41.3 |
How is fuel oil made?
The first part of refining crude oil is to heat it until it boils. The boiling liquid is separated into different liquids and gases in a distillation column. These liquids are used to make petrol, paraffin, diesel fuel etc. The gases cool down as they go up the column until they condense (turn back into liquid again).
Is diesel a light fuel oil?
No. 1 Diesel Fuel: A light distillate fuel oil that has distillation temperatures of 550 degrees Fahrenheit at the 90-percent point and meets the specifications defined in ASTM Specification D 975. It is used in high-speed diesel engines, such as those in city buses and similar vehicles.
What is No 1 fuel oil?
No. 1 Fuel Oil: A light distillate fuel oil that has distillation temperatures of 400 degrees Fahrenheit at the 10-percent recovery point and 550 degrees Fahrenheit at the 90-percent point and meets the specifications defined in ASTM Specification D 396.
What kind of fuel oil is used in a truck?
No. 2 is the diesel that trucks and some cars run on, leading to the name “road diesel”. It is the same thing as heating oil. [citation needed] No. 3 is a distillate fuel oil and is rarely used. No. 4 fuel oil is usually a blend of distillate and residual fuel oils, such as No. 2 and 6; however, sometimes it is just a heavy distillate.
What’s the difference between number 3 and 4 fuel oil?
Number 3 fuel oil was a distillate oil for burners requiring low-viscosity fuel. ASTM merged this grade into the number 2 specification, and the term has been rarely used since the mid-20th century. Number 4 fuel oil is a commercial heating oil for burner installations not equipped with preheaters.
Which is heavier No.5 or No.6 fuel oil?
As far more No. 6 than No. 5 is produced, the terms heavy fuel oil and residual fuel oil are sometimes used as synonyms for No. 6. They are what remains of the crude oil after gasoline and the distillate fuel oils are extracted through distillation. No. 5 fuel oil is a mixture of No. 6 (about 75-80%) with No. 2.
What kind of fuel oil is diesel made of?
In this sense, diesel is a type of fuel oil. Fuel oil is made of long hydrocarbon chains, particularly alkanes, cycloalkanes and aromatics. The term fuel oil is also used in a stricter sense to refer only to the heaviest commercial fuel that can be obtained from crude oil, heavier than gasoline and naphtha.
