Three concentric and rotating shafts would be known as a contra-rotating device. Currently, several machines like these are being designed, according to the US Patent Office.

My apologies... I got it wrong... it is just the material continually in contact with the flow in a valve.

Thank you anyway...

A flexible steel rule is similar to a rigid steel rule but it is easier to bend and it does not retain shape when bent, but springs back to it's original straight shape. You use it to measure length or distance. You can also use it to whack (hit) things, but don't do your little brother or he'll tell Mom.

It can be a new variable eg x*y = xy.

Or it can be a constant eg x is a variable then 3/x is another variable. x*(3/x) = 3, which is a constant.

A firm would usually do that because it expects to sell the product, and make a profit.

At the company I work for, we send signals to orbit with 1 watt, but I'm sure it could be done with less. However, it depends on how fast a datarate you want, more power can generally get you a higher datarate.

Yes. BS 6651 has been replaced by BS EN 62305.

Yep, but can also be Ante Meridian. Before noon.

A hydraulic miner is commonly referred to as a "hydraulic miner" or simply a "hydraulic placer miner." This type of miner uses high-pressure water jets to dislodge and wash away soil and rock, allowing them to extract valuable minerals, particularly gold, from alluvial deposits. The technique is often associated with historical gold mining during the 19th century, especially in regions like California.

Some are electronic, and some old ones use a blower motor to blow air into the chopper. The chopper kind of chops the air. It is then blown out a horn

A runway must be smooth in order for an airplane to land safely on it.

In a general perspective: The initial stage of production for both products will be at the same refinery, from the same raw material. Obviously the lubricating oil has a different composition than petrol/ gas/ combustible fuel, so the difference is at which point in the refinement process the hydrocarbons (molecules composed of carbon and hydrogen) are extracted from the raw material.

After the raw material is heated to a gaseous state, the hot gas will cool as it rises through the distillation column. Since different hydrocarbons have different boiling points, they will condensate at different points in the column and be collected. This is how the compounds used in lubricating oils, fuels, plastics, etc. are separated from the raw material. This process is known as fractional distillation.

These distilled products may undergo further distillation and refinement, and different chemicals may be added prior to shipment to the consumer/industrial markets.

A plait point is a term used in liquid-liquid extraction. It is the point where all three phases (in a ternary diagram) are partially soluble in each other. (excuse me if this is wrong)

Force acting on a substance in a direction perpendicular to the extension of the substance, as for example the pressure of air along the front of an airplane wing. Shear forces often result in shear strain. Resistance to such forces in a fluid is linked to its viscosity. Also called shearing force .

A tool that uses a hammer like rotary action to release very tight nuts.

The structure is called a over reinforced concrete or structure. The structure can fail without warning. Discuss why managers she would always t
