What are cooling towers for?

What is the Purpose of a Cooling Tower?

A Cooling Tower is used with industrial applications that produce waste heat as a byproduct of their operations. These applications may include air-conditioning, manufacturing, and power generation. Cooling Towers provide an energy efficient and environmentally-friendly means of rejecting that waste heat, saving our natural bodies of water from receiving vast quantities of warm water that would threaten marine life and ecology. They work instead to dissipate evaporated water into the atmosphere, allowing wind and air circulation to diffuse the heat.

Can you re-use thermoplastic?

Basically there are two types of thermoplastic, thermoset and thermoform. Thermoset becomes hard when heated an example would be Bakelite. A thermoform plastic gets soft when heated and can be reformed. An example would be abs such as used in plastic pipe.

Where can you buy a stretch wrap machine?

Shrink wrap is used to help wrap something tight and keep it from moving or shifting. Shrink wrap machines come in various sizes and can be purchased from Office Zone as well as Staples. They each have various sizes and models available to purchase.

How are printed circuit boards manufactured?

Printed circuit board are electronic circuits created by mounting electronic components on anonconductive board, and creating conductive connections between them. The creation ofcircuit patterns is accomplished using both additive and subtractive methods. The conductivecircuit is generally copper, although aluminum, nickel, chrome, and other metals are sometimesused. There are three basic varieties of printed circuit boards: single-sided, double-sided, andmulti-layered. The spatial and density requirement, and the circuitry complexity determine thetype of board produced. Printed circuit boards are employed in the manufacturing of businessmachines and computers, as well as communication, control, and home entertainment equip-ment.

What are thermoplastics used for?

Chairs, boxes, sterilizeable equipment, bottles, helmlets, gasoline deposits, gloves, lenses, "lego", lights and other ilumination accessories, automobile interiors, textile fibres, police shields, fishing guear, etc...

What is a temperature well in piping?

Do you mean 'thermal well'? If so, a thermal well is a tube that is inserted into a process pipe. Then a thermocouple is inserted into the tube to measure the temperature of the process. (Gas, steam, water, etc.)

How many psi is 1 bar?

Pounds per Square Inch or Psi is a unit of pressure or stress. 1 bar is equal to 14.50377 Psi.

Difference between mild steel and high tensile steel?

About a decade ago, a consortium of thirty-five steel companies worldwide undertook a massive programme to design, build, and test an UltraLight Steel Auto Body (ULSAB).W-1. ULSAB proved to be lightweight, structurally sound, safe, executable and affordable. One of the major contributors to the success of the ULSAB was a group of new steel types and grades called Advanced High Strength Steels (AHSS) (or ultra high-tensile steel).

The main reason to utilize AHSS is their better performance in crash energy management, which allows one to down gauge with AHSS. In addition, these engineered AHSS address the automotive industry's need for steels with higher strength than conventional mild steels and enhanced formability. The DP (Dual phase) and TRIP (Transformation induced plasticity) steels may provide additional stretchability (but not bendability) compared to conventional steels such as HSLA steels within the same strength range. The CP (Complex phase) and MS (Martensitic) steels extend the strength range while maintaining the same formability.

While the ULSAB proved these AHSS provided a major benefit to the automotive industry, these steels reacted differently from traditional higher strength steels in forming and assembly. Worldwide working groups within the WorldAutoSteel organization created the AHSS Application Guidelines (See the link below) to explain how and why AHSS steels were different from traditional mild and higher strength steels in terms of press-forming, fabrication, and joining processes for automotive underbody, structural, and body panels designed for higher strength steels.

What type of simple machine is a toothed wheel that fits into another toothed wheel?

If you think about this, you can figure it out. What shape is a shark's tooth? It's a triangle, right? What machine is a triangle shape? The only simple machine that looks like a triangle is a wedge.

Types of rectifier?

There are basically two types of rectifiers one is the half wave rectifier and the other is the full wave rectifies. The full wave rectifier is further classified into two types namely the bridge rectifier and the center tapped rectifier.There are also silicon controlled rectifiers nowadays.

What personal protective ppe equipment do you need to wear for the engineering activitee being undertaken?

It depends on the type of work one proposes to carry out. With height work, working with electricity, handling chemicals etc, different PPEs are used. Answer could be more specific, if the question too is specific.

How big is 5 microns?

The micron is 1 x 10-6 meters, so 5 microns is 5 x 10-6 meters. This is also 0.005 millimeters, or 0.000197 inches.

What are different numeric constraints?

  1. a constraint that deals with the complexity of an object.
  2. a constraint that deals with numbers and shapes.
  3. a constraint that... oh I don't know.
  4. lol i just made this all up.
  5. A constraint that can be described by a number value etc... 5 feet long, three inches tall

What is the disadvantages of centrifugal compressor?

A centrifugal pump cannot pump air, therefore cannot self prime, like a positive displacement pump.

Device to increase speed of spinning shaft?

This depends on several considerations.

Need a single shaft to increase speed. Apply additional torque

Need a shaft in a series of shafts to run faster, change the drive ratio.

And so on.

What is the difference between an SCR and a TRIAC?

A thyristor is another name for an SCR, which stands for Silicon Controlled Rectifier.

Thyristors or SCRs are bi-directional devices used to control the flow of AC current. Once triggered, the device remains "on" until the next wave of current crosses zero after the trigger is removed.

For more information about thyristors or SCRs see the Related link shown below.

What metals are in duralium?

Alloy of aluminum (over 90%) with copper (about 4%), magnesium (0.5%-1%), and manganese (less than 1%).

Is mild steel better than stainless steel?

Per the attached related link, the density (hence weight) of stainless is slightly more than the mild carbon steel. Using about 8.03/7.84 ratio of density, for the same volume of material the stainless will weigh 2.4 % more.
