Why Is the Storage Tank for Fuel in Fuel Tankers Always Cylindrical?

Why is the storage tank for fuel in fuel tankers always cylindrical?

It might be not precisely cylindrical, often ellipsoidal. But the reason behind this is rigidity. Sush a tank will not bulge due to the fuel weight

Nuclear fuel

To be a useful fuel for nuclear fission chain reactions, the material must: Be in the region of the binding energy curve where a fission chain reaction is possible (i.e., above radium) Have a high probability of fission on neutron capture Release more than one neutron on average per neutron capture. (Enough of them on each fission, to compensate for nonfissions, and absorptions in the moderator) Have a reasonably long half-life Be available in suitable quantitiesFissile nuclides in nuclear fuels include: Uranium-235 which occurs in natural uranium and enriched uranium Plutonium-239 bred from uranium-238 by neutron capture Plutonium-241 bred from plutonium-240 by neutron capture. The 240Pu comes from 239Pu by the same process. Uranium-233 bred from thorium-232 by neutron captureFissile nuclides do not have a 100% chance of undergoing fission on absorption of a neutron. The chance is dependent on the nuclide as well as neutron energy. For low and medium-energy neutrons, the neutron capture cross sections for fission (F), the cross section for neutron capture with emission of a gamma ray (), and the percentage of non-fissions are in the table at right.

Common causes that cause Fuel to be too rich?

I went back to read your previous question. Your fuel mixture is not too rich, you have a misfire, which was diagnosed from the trouble code you posted. That's the problem, you need to figure out why that cylinder is misfiring. Could be a burnt valve, broken rings or several other reasons. The cylinder does not fire and the fuel in that cylinder does not get burnt causing the O2 sensors to tell the ECU that there is a problem. Fix the misfire, you fix the trouble codes for it, and the O2 sensors.

Top Fuel

Top Fuel dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 335 miles per hour (539 km/h) and finishing the 1,000 foot (305 m) runs in 3.62 seconds. A top fuel dragster accelerates from a standstill to 100 mph (160 km/h) in as little as 0.8 seconds (less than one third the time required by a production Porsche 911 Turbo to reach 60 mph (100 km/h)) and can exceed 280 mph (450 km/h) in just 660 feet (200 m). This subjects the driver to an average acceleration of about 4.0 g0 (39 m/s2) over the duration of the race and with a peak of over 5.6 g0 (55 m/s2). Because of the speeds, this class exclusively races to only a 1,000 foot (305 m) distance, and not the traditional 1,320 feet (400 m). The rule was changed in 2008 by the National Hot Rod Association following the fatal crash of Funny Car driver Scott Kalitta during a qualifying session at Old Bridge Township Raceway Park in Englishtown, New Jersey, USA. The shortening of the distance was used in the FIA at some tracks, and as of 2012 is now the standard Top Fuel distance by the FIA. The International Hot Rod Association, which now sanctions Top Fuel in Australia, dropped the distance in September 2017 after Santo Rapisarda, a car owner who often runs NHRA races in the United States, pushed for the change. In recent years, only exhibition races in Martin, Michigan's US 131 Motorsports Park are run as Top Fuel races to the quarter mile.

What are five factors that influence the value of fuel?

Iu2019m interested. This is a good question. Were you asked this in a class? PM me if the answer is uncomfortable on any level.Answers may vary but:The price of the raw material of the fuel. Think about it a bit. Manure is used as a fuel not because itu2019s efficient, but because it is cheap. The price of refining the fuel. Think about it. If itu2019s economically less expensive, which, in itself, is a complicated notion, itu2019s possible that a less refined fuel may be less expensive even though it is more energy dense and efficient just because it is FISCALLY less expensive. (I HATE BTU based analysis because itu2019s so incredibly shallow and engineers love it, butu2026 gaaah). If I can generate more work based on units close to me that I can get for free or at a lesser cost, that will sometimes economically defeat a refined fuel, which overall makes better use of the physical energy stored in the chemical bonds. The distance that one has to transport the fuel. Thatu2019s easy. The more fuel that it takes to transport the fuel, the more expensive the fuel is locally. If I have coal sticking out of a vein on my farm, Iu2019m gonna use it, because the cost to me is zero. If the coal seam is exposed on my neighboru2019s farm, itu2019s more iffy, because I have to pay someone to mine and send it to me. It gets progressively worse as the distance increases.The energy density of the fuel influences the value. High energy density fuels trade for crazy higher values. As an illustration, the cost of a barrel of crude oil is currently $16.94. A barrel of crude weighs around 135 kg (depending on grade, blah, blah, blah, but thatu2019s not a bad average). 135 kg of uranium, which has an insanely higher energy density is USD 10, 500 or so.What you can DO with the fuel (or reallyu2026 substance, in this case) matters. In the case of crude oil, itu2019su2026 insane that weu2019re taking a substance that cooked in the ground for millions of years and BURNING it for the value of the solar energy in its chemical bonds. No, we should be using this for crafting, basically. Itu2019s also crazy good for agriculture, since we use feedstock from it to built nitrates used for fertilizer which feeds the world, which is over its carrying capacity otherwise. So, if this "other stuff" (like eating food) starts to matter more than driving to McDonalds (which is dumb), then, all of a sudden, your fuel IS food, and food wins on Maslowu2019s hierarchy of needs.
