What is the difference between a weldolet and a sockolet?
Weldolet and Sockolet are basically self reinforced fittings. Weldolet is used for Butt weld branch connection where standard tee is not available due to size restrictions and the piping is of critical / high pressure service. Sockolet is used for socket welding branch connection, which require reinforcing pad.

1.Air exerts pressure.
2.Air has weight and volume.
3.Air takes up space.
4. Air can be compressed.
5. Air moves fluidly.
6. Air can hold/push/pull things.
7. Air reacts to temperature. (expands when heated, shrinks when cold)
THAT'S ALL FOLKS!
How do you produce soy acid oil from soapstock?
la borra o jabón se hace reaccionar con acido sulfurico en forma estequiometrica mas un exceso de 20%, a una temperatura de 70-80°c, se agita durante un par de horas y se deja decantar el agua, luego de eliminar el agua se lava con mas agua hasta que esta de un pH superior a 5, para comprobar que a reaccionado todo el ácido se puede determinar el contenido de jabón remanente en el ácido graso formado.
Acid hydrolysis using sulphuric acid and water (equilibrium reaction). The ester splits into a carboxylic acid and alcohol, protons donated from the acid. The solution can then be distilled and the remaining acid can be checked using UV indicator. Acid hydrolysis using sulphuric acid and water (equilibrium reaction).

Composition of hydrocarbons in crude oil?
Crude oil has oxygen, carbon dioxide and gastro hemus in it.
No, Polyurethane is not toxic. In bedding products it often gives off a strong scent for a few days, which is not harmful. It is also used in MANY eco-friendly products, because it is non-toxic. It is a type of plastic, and can be used in place of nearly everything from metal to fiberglass to beds. It's a great discover I would say.
NOT TRUE, SIR, as I was personally being poisoned by exposure to the off-gassing, and my health only improved after replacing the mattress. I also personally know several other local people who have been similarly affected. Please get the whole truth before you assure people of something like this.
What is the importance of technical drawing to chemical engineering?
Without a prior layout and planned idea, you're basically winging your design and most likely messing up your final product. So drawing is one of the most important steps of planning and IT IS in fact EXTREMELY important in engineering.
Why thermal conductivity value is important in engineering?
The Thermal Conductivity Value is important because it allows engineers or anyone find a material that insulates something like a shuttle to make sure that the extreme heat of re-entry or the extreme cold of space travel will not come in and boil astronauts or freeze them out. The lower the Thermal Conductivity Value the better it insulates.
What does polyethylene look like?
Polythene, also known as polyethene is a polymer made up of ethene monomers. They are joined up together in a long chain to form poylethene. Polyethene is a plastic what burns well and is insoluble in water.
What is the difference between density and specific heat?
Density has dimensions of: mass/volume
for example: the density of water at 4 °C is 1.000 g/cm3
Specific heat has dimensions of: energy/(mass·temperature)
for example: the specific heat of water is about 1 calorie/g·°C
Its done with a fame or torch, you heat the copper to a almost cherry red glow, (caution, you don't want it red, if it just starts to glow, "stop" that where you just annealed copper.
but the more you shape it after your annealing process it will harden up again, not due to cooling but due to your shaping it
Do you capitalize Chemical Engineering?
As a title of a school course, yes. As a word in a sentence such as, "The drug affected his brain chemistry," no.

What are some samples of corporate mission statements?
Since this question was placed in the "cars and vehicles" category, I would assume you were looking for automotive-related mission statements. If that's the case, you can go to just about any major automotive vehicle manufacturer's website like GM, Toyota, Honda, Mercedes, etc. and you'll find their mission statement somewhere on the site.
WHAT IS Conceptual engineering in design activity?
The conceptual engineering aims to identify the machinery, equipment, supplies and facilities necessary to operate a project.
By definition:
A conceptual engineering study should logically consider the issues, concerns and goals that may be raised by an engineering request, evaluate possible technical solutions and clearly report the findings and recommendations. It is intended to provide a comparative basis for decision making regarding further actions, without expenditure of exhaustive engineering efforts. Further preliminary engineering (e.g., equipment layouts, geological studies, testing and inspections) may then be suggested for the recommended conceptual solution prior to full project funding commitment and detailed engineering design.
What is the element that is used in rockets as an igniter?
There are a fair few ingredients used in fireworks, the ones that are used in their elemental form are:
Sulphur, Silicon, Carbon, Red Phosphorus, Magnesium, Aluminium, Titanium, Boron, Zirconium, Copper, Iron.
Who was the inventor of the water purification device?
Reverse osmosis is one processing device in which the TDS of water is removed.There are other devices which use ultra violet rays to kill or numb the bacteria also.Devices should be used only after a clear check of the dissolved substances in the water.Chances are that needed minerals may be removed in these process.
The boiling point of alcohol can vary depending on the type of alcohol. For example, the boiling point of ethanol (found in alcoholic beverages) is around 78.37°C (173.07°F). Isopropyl alcohol, often used as rubbing alcohol, has a boiling point of around 82.6°C (180.7°F).
You need to look at the misconception that time is a dimension, and that traveling its length is even possible. Though often described as such, it is not a dimension. It is a descriptive attribute, like a pound, or velocity, or a color. Time is simply a description of comparative change, for without comparative change between two objects, there is no such thing as time: whether it is comparing the rate of molecule decay, or the comparative change of chemical reactions. In an absolute pure vacuum - time does not exist. And since time is not a constant - it cannot be a dimension.
To qualify as a dimension, the dimension has to exist in the same space and time as all of the other dimensions. Meaning it must always be present, and therefore, a constant. The dimensions are length, width, breadth, and energy. Why energy? because it is always present in all physical objects, occupying the same space and time as all the other dimensions. Various frequencies of energy may in themselves be additional dimensions.
To address the issue of time travel: to reverse time-you would have to know the pre-existing condition of every molecular and chemical reaction in the universe, and somehow reverse them all, simultaneously, to their previous positions and states.
Meaning: you would also have to be restored. So, you would never know about the future, and never realize you have traveled back in time. Leaving the times and events to replay themselves back out exactly as they did before... So, what would be the point?
If you travel back in time to kill your own grandfather... 1) you would never know it... 2) History has already shown us what happened - since you're being in the past has always been the way it originally happened - making you part of the original, and only, timeline - we know you fail in your attempt. 3) If you popped backwards a few decades - the Earth would not be here for you to land upon. It would be 100's of light years back in its orbit around the Milkyway Galaxy. So, until you can travel 100's of light years in the blink of an eye - there would be no point in time travel...
A few points SciFi overlooks when writing movies and novels...
Now, if you wished to go on a one way trip to the future - you simply need to find a way to enter a form of biological suspended animation for the appropriate time period. When you awaken, you will be in the future, and it will have appeared, from you relative position, that it occurred instantly...
Why is water as a good conductor of electricity cannot be used as a cable?
Normally cables are made from either Aluminium or Copper as these are the two best cunductors apart from Silvier which is too expensive. These materials are ideal for use as cables as they can be easily shaped. Water is a liquid and therefore could not be used to make a wire as a solid is needed for this.
add and as soon as you've gotten more than a couple of volts, the water will be electrolysed into hydrogen and Oxygen.
What is the density of diesel 80 degrees C?
For a diesel with a density of 843 kg/m3 @ 15.6°C, the density at 80°C would be 803 kg/m3.
For reference, the EURO-V specification for diesel requires a specific gravity of 0.820 to 0.845 @ 15.6°C. The diesel above is on the heavier side of the specification. Since the composition of diesel may depend on local specifications, the composition and density may vary for region to region and even refinery to refinery.
