Oil Definition and 552 Threads

there are a lot of natural preservatives. vinegar, alcohol, sugar, salt, oil. what is the best? Is there any predominant research about this topic?

when Robert Millikan did the oil drop experiment to measure the charge of an electron . they balanced the gravitational force of the oil drop with the electric field . did they use F=qE , did they know how many electrons were in their oil drops .

From what I have read: Tar causes cancer in road crews and smokers, gasoline causes leukemia in neighbors to gas stations and petroleum plants, benzene causes bladder cancer and leukemia in rubber workers - how about the BP bio-poisoning?

Im having a discussion with someone about sanctions leading up to the war in Iraq. I was wondering if anyone could give me a source which shows where the money went in that program (corruption), and what country the Iraqi oil went to.

Its not a secret that the human race runs on 3 essential liquids; water, beer and oil. Mother nature gifts us the first, we know how to cook the second but the third is somewhat problematic. What alternatives we have now, nuclear power for electricity? But what will happen in the transportation...

Ok here's a basic idea that I read somewhere else. See the attached image. Basically, its a pipe with inflatable "tires" surrounding it, that will be inserted into the well, and then the "tires" pumped full of hydrolic fluid. Hopefully capping the well, while still being able to retrieve oil...

You can obtain a rough estimate of the size of a molecule with the following simple experiment: Let a droplet of oil spread out on a fairly large but smooth water surface. The resulting ”oil slick” that forms on the surface of the water will be approximately one molecule thick. Given an oil...

Hello all, It's my first post. I'm french Canadian so I may make grammar mistakes in English :-) This is a question I'm asking me since yesterday. It's about the oil spill in the Gulf of Mexico. The oil and gases are less dense than the salted water. The breach is at about 1500 meters...

Hey guys, any of you interested in following precisely the next step in BP's attempt to fix the oil leak in the Gulf? I'd be interested in "exactly" what they're planning. However, I'm not familiar with the sub-sea design. For example, I assume there is a 20" well bore below the sea bed...

It seems to me that BP's first idea of putting a big funnel over the top of the leak was a good start, they just didn't expect so much methane hydrate slush to clog the funnel. What they need to do is to build a simple heat exchanger inside the funnel and pump warm Gulf water through it to...

I have attached a word document showing an image and some typed out simple calculations. I am working on an oil containment system for a new building my employer is going to be building soon. Its pretty simple in the middle of the floor we put a catch basin with a 24"x24" grate. This catch...

What would happen if a hurricane swept through the gulf over the area of the spill? How would the oil effect water temp., which contributes to hurricane strength? Would a hurricane pick-up and disperse the oil inland if it made land-fall?...or would a hurricane basically spread the oil out so...

http://www.telegraph.co.uk/finance/newsbysector/energy/oilandgas/7726142/Barack-Obama-sends-nuclear-experts-to-tackle-BPs-Gulf-of-Mexico-oil-leak.html I don't know a damn thing about nuclear physics so can anyone shed some light here? How does this apply to nuclear physics? What are some of...

http://www.cnn.com/2010/US/05/19/gulf.oil.spill/index.html now we will also be getting a live feed, per congressional demand, and this is now BP's "new hope": Top-Kill, not to be confused with the Top Hat, Large containment structure, Junk Shot... and so forth. Sen. Bill Nelson and...

this oil leak in the Gulf has got me wondering about a few things. There are a lot of questions being asked and the only answers seem vague and uninformed. I'm new here so bear with me as I learn the etiquette. My primary question is why is this oil staying near the bottom when its STP...

In the thread in P&WA on the issue of the oil spill, I expressed my skepticism that the rate of the spill could be accurately measured via analysis of underwater video clips. That skepticism was strengthened by the recent statement by Prof Steven Wereley, the originator of the first such...

I noticed that when i was working on my car today that when i spilled oil on the ground in the sun it looked as if it had a bunch of colors in it. I know that used oil is black and black absorbs light. So why does it show all of these colors?

hello everyone, we have to design a procedure to determine the mass of an individual object inside a bag which is filled with many of these identical objects ( one kind) For ex. Bag 1; mass = 435.6, filled with candy- find mass of individual candy. we have: 10 bags of one candy 10...

Hi everyone, I was looking at some data from the Energy Information Association (http://www.eia.doe.gov/emeu/mecs/mecs2006/pdf/Table3_2.pdf\) about the fuel used by different industrial processes. Under the industry of "Petroleum Refining," there is a bit of natural gas and electricity used...

Hi, I understand that the iodine number is the number of moles of iodine reacting with one mole of fat/oil which indicates the number of double bonds present in the fat/oil molecule. However I am having trouble calculating them. Can someone show me how to solve the following question...

Homework Statement In an early set of experiments, Milikan observed that the following measure charges, among others, appeared at different times on a single oil drop. What value of elementary charge can be deduced from these data? 1) 6.563 x 10^-19 C 2) 8.204 x 10^-19 C 3) 11.50 x...

could someone please help me? what would the divergence, gradient and curl of an oil spill be? I'm a bit confused. Thank you

I was wondering if someone could explain how ice crystals are being formed in the tank/pipeline BP is trying to use to stem the flood of oil pumping into the ocean. A friend and me were discussing it and a few questions came to mind about it, not just related to this issue. He suggested that...

Can someone explain why with the tremendous pressure of- is it 5000 ft. of water-pushing down that oil can still leak out? I guess the oil pressure must be greater. How do you calculate the water pressure at that depth on the broken pipe. If the pipe is say one foot diameter would you figure...

I have made some bread boards out of hardwood & heard to preserve them you coat with Mineral oil. I can't find any locally & was hoping there is something else i can use?

Hello everyone, i had one doubt in my mind regarding Rotary oil pump. The Question is what would happen if we remove oil from the Rotary oil pump. What would be its effects? Please Reply Regards Gagan Sharma :confused:

Is that possible? UH offers a physics degree BS with geophysics specialization. I looked at doing that a while back but decided against it. With just a BS Physics, could I get into oil and gas/energy? If so, what kinds of jobs would I be doing? I live outside of Houston, btw.

Homework Statement What fractions of crude oil would be distilled off, if you did the fractional distillation of crude oil in a lab? Homework Equations The Attempt at a Solution I think light petroleum and light naphtha, but I am not sure.

In normal conditions, it takes a long time for wood to burn. But if you add some oil (or something similar like butter) it tends to burn faster. So, does adding such additives increase the calorific value? What makes the wood burn faster? Is the "faster" burning of wood and calorific value...

Here in the NW most homes are or were heated by oil. The biggest cost of switching to gas (as geothermal is very expensive) is decommissioning the old buried oil tank, in many cases up to 675 gal. cap. I was pondering weather the old tank could be filled with a solution and somehow figure out...

Before I get flamed for this, I am not running a gasoline engine directly with normal fuel oil or veg oil- I made a gasifier. My gasifier is lame at the moment, but is just for testing purposes. It consists of a small fuel reservoir, suspended several feet up, then it flows down through about...
