Hi guys, For a prac we did, we are given the properties of a particular oil. Density (kg/m^3) = 876 Viscosity (Ns/m^2) = 20.0x10^(-3) I believe it is the dynamic viscosity. Now is this viscosity correct? Or should it be 2.0x10^(-3)

About 200 days ago i made a thread on this forum about peak oil the thread was called hubbert peak. in that post i asked if you realized that peak oil was coming and got by and large a negative response. things like "no peak oil is myth" and "we will find other energy sources" i...

For those of you who know about my efforts to join the biofuels industry, we did in fact have algae oil by Labor Day, which was the goal this summer. One of my short cuts failed so for now we only got a few grams extracted, with the rest still in the algae, but a number of tests seem to confirm...

Does anyone know of any chemicals that will vulcanize soybean oil? I only know of two chemicals at the moment- Magnesium oxide, and sulfur. I have tried these chemicals and they do work. The one made with magesium oxide is very shapeable and deforms into a blob if left alone.

My chemistry professor was discussing Milikan's oil drop experiment today, and she said that he determined the mass of the oil drop by measuring its speed as it fell. (I found this further description online) If that's the case, why doesn't air resistence appear in the equation Eq=mg from which...

I found that the leaves of the elderberry tree (Sambucus nigra) can be used to add a green coloring to oils and fats, among other things, is this claim true? http://www.pfaf.org/database/plants.php?Sambucus+nigra" Also what compound in the edible berries makes it a good pH indicator (red=acid...

In 1956, Hubbert proposed that fossil fuel production in a given region over time would follow a bell-shaped curve without giving a precise formula; he later used the Hubbert curve, the derivative of the logistic curve, for estimating future production. Hubbert assumed that after fossil fuel...

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 10^-19 C 4) 13.13 x 10^-19...

Hi I've got a scenario and would like a confirmation or rejection on it's correctness. If i lower a steel riser (for simplicity it is 3000 m and vertical, open ended, cylindrical steel pipe, completely flush) into drilling mud (assume water) the surface weight would be the steel weight in...

One time I made an oil that burned cooler than normal (or so I think) and has a persistent flame (in light wind it would not go out when a candle flame would). Burns better than Regular canola oil. I made it by melting sulphur in the bottom of a metal dish then pouring canola oil on top then...

How is it possible that the United States is about the only country that allows these drug ("snake oil sellers) advertisements on T. V.? They are of insignificant value to the general viewer. How do other countries ban such a nuisance. I would suggest that we contact these T. V. stations and...

If water and vegetable oil are added to a bowl, they do not mix. If gasoline and vegetable oil are added in another bowl, they _do_ mix. this has something to do with the polarity of the molecules, i.e. water is polar and gasoline and vegetable oil are unpolar. But is it possible to...

So I'm starting to read up on some of this stuff on the internet but most the argument counterargument seems to be from the same sources Gold vs peak oil theorist. Is this debate so far concluded in academics that no research is being published in journals? What is the curret status of the...

ok, this is more of a question of theory than actual calculation. Me and my friends did a physics lab on heat transfer vs. surface area of contact. We used water and oil (since oil will float above the water and creating a surface of contact). We heated the water to ~50 degrees C and oil was...

"I think energy independence is going too far" - Shell Oil http://www.msnbc.msn.com/id/13296235/page/5/ I think it is clear that this is not who we need making the calls for what's good for the US. Energy needs to be taken out of the hands of big oil...

Hi everybody, didn't really know where to put this thread since it's physics using math, so I'm sorry if it's not in its appropriate place. My problem is: I need to compute the mass of oil in a cylindrical core put into a core holder.it's partially filled of oil. I didn't know how to...

My question is that why did Millikan allow the oil drop to fall in terminal velocity and thus solving for the radius of the oil drop to find its mass eventually and not using a microscope to measure the oil drop's radius? This is one part of my tutorial question and I really have no idea...

I was wondering about this and haven't had the chance to look into it. Who is getting the money from the Iraqi oil sold? They are supposed to be at ~50% of pre-war production levels. And who is monitoring oil production and sales?

Hello everyone, as you may well know gas prices are high and will probably remain high for a little while. Yet, there is one thing people rarely talk about and that is that oil is a non renewable resource and there is only a finite amount left in the earth. In the long run gas prices will...
