It is science, though many times confused as being the same thing.
I'll prove my point. You know that I could never have been inside of your mysterious building out there, and I imagine you can be sure no one has told me its secrets.
Yet I'll bet that I can describe fairly accurately what is in there—not from seeing the machinery, but from knowing what must be done to oil in order to get the products you need. You want to hear? Your crude oil runs into a tank of some kind, and you pipe it from there to a retortsome big vessel that you can seal airtight.
Once it is closed, you light a fire under the thing and try to get all the oil to an even temperature. A gas rises from the oil and you take it off through a pipe and run it through a condenserprobably more pipe with water running over it.
Only my family have seen, no others—I'll swear to that! I told you that we have been doing this stuff for years in my country. I'm not out to steal your secrets. In fact, they are pretty small potatoes where I come from, where every farmer has a still for cooking up his own mash and saving on taxes.
I'll bet I can even put in some improvements for you, sight unseen. How do you monitor the temperature on your cooking brew?
Do you have thermometers? I can see where your bootleg joy-juice is going to take a big jump in quality, if you have anyone here who can do some simple glass-blowing.
Though it might be easier to rig up a coiled bi-metallic strip. You're trying to boil off your various fractions, and unless you keep an even and controlled temperature you are going to have a mixed brew. The thing you want for your engines are the most volatile fractions, the liquids that boil off first, like gasoline and benzene.
After that you raise the temperature and collect kerosene for your lamps, and so forth right on down the line until you have a nice mass of tar left to pave your roads with. How does that sound to you?
But I am not interested in your thermometer nor in improving our water-of-power. It has been good enough for my family for generations and it is good enough for me. Stripping away the 'shrines' and 'sacred powers,' I would say that you go into the engine room to do a piece of work with very little praying involved.
There could be a number of ways of moving those vehiclesbut let's think of the simplest. This is top of the head now, so no penalties if I miss any of the fine points.
Internal combustion is out. I doubt if you have the technology to handle it, plus the fact there was a lot of do about the water tank and it took you almost an hour to get under way. That sounds as if you were getting up a head of steam —The safety valve!
I forgot about that. You go in, lock the door, of course, then open a couple of valves until the fuel drips into the firebox, then you light it. Maybe you have a pressure gaugeor maybe you just wait until the safety valve pops to tell you if you have a head of steam.
Which can be dangerous, since a sticking valve could blow the whole works right over the mountain. Once you have the steam, you crack a valve to let it into the cylinders and get the thing moving.Middle School Lesson Plans. Browse the entire collection of Middle School Lesson Plans.
Applied Sciences, an international, peer-reviewed Open Access journal. Essay about Fractional Distillation Organic Lab Report This experiment aims to (1) compare the efficiency of simple and fractional distillation, (2) distill and calculate the % of ethanol and (3) determine the % loss in distillation.
Two set-ups were made in the. There are many different ways of distilling, but this experiment uses fractional distillation as the method for extracting ethanol from a mixture. Essay Distillation and Fraction Distillation Lab Report; Section 2 – to Distillation and Fractional Distillation Distillation and Fraction Distillations Purpose: The purpose of distillation is to purify a liquid.
Distillations are use to purify contaminates out of water to obtain clean pure water, as well as, to separate. "Technological advance is an inherently iterative process. One does not simply take sand from the beach and produce a Dataprobe.
We use crude tools to fashion better tools, and then our better tools to fashion more precise tools, and so on.
