Answer:

filter drier

Explanation:

Any refrigeration or air conditioning system needs filter driers as a crucial part. In a refrigeration or air conditioning system, a filter drier serves two crucial purposes: first, it adsorbs system impurities like water, which can produce acids, and second, it provides physical filtering. To guarantee optimal and cost-effective dryer design, each component must be evaluated. The most crucial role of a dryer is to be able to drain water from a refrigeration system. Water can originate from a variety of places, including motor windings, equipment leaks, retained air from poor drainage, and others.

Why do electricians require critical thinking skills? In order to logically identify alternative solutions to problems in order

Rina8888 [55]

Answer:

In order to logically identify alternative solutions to problems

Explanation:

Electricians are specialized in electrical wiring of buildings, transmission lines, stationary machines, and related equipment. They are either employed in the installations of new electrical components, or to maintain an already installed component. The job of an electrician can be mentally tasking, especially in troubleshooting for fault, and methods of fixing of faults. Some problems might require an out-of-norm approach to solve, and the electrician has to be able to logically identify alternative solutions to problems.

Compute the repeat unit molecular weight of PTFE. Also compute the number-average molecular weight for a PTFE for which the degr

MatroZZZ [7]

Answer:

a) the repeat unit molecular weight of PTFE MW = 100.015 g/mole

b) the number-average molecular weight for a PTFE for which the degree of polymerization is 10,000 щₙ = 1000150 g/mole

Explanation:

Given that;

PTFE which is also called Polytetrafluoroethylene

structure of repeat unit of Polytetrafluoroethylene

(C2F4)n

To compute the repeat unit molecular weight

we say

MW = 2( atomic weight of C ) + 4( atomic weight of F)

MW = 2 (12.0107) + 4 ( 18.9984)

MW = 100.015 g/mole

therefore the repeat unit molecular weight of PTFE MW = 100.015 g/mole

To compute the number-average molecular weight for PTFE of which the degree of polymerization is 10,000

we say

DP = щₙ / MW

where щₙ is the number of average molecular weight,

MW is the repeat unit molecular weight give as 100.015 g/mole

DP is degree of polymerization which is 10,000

Now we substitute

10,000 = щₙ / 100.015

щₙ = 10,000 × 100.015

щₙ = 1000150 g/mole

Therefore the number-average molecular weight for a PTFE for which the degree of polymerization is 10,000 щₙ = 1000150 g/mole

Mechanical clips are used to close bags and keep things together. Investigate the design of various paper clips, hair clips, and

pochemuha

Answer:

Hair clip: this used to hold human hairs together especially long hairs

The Design parameters to be considered are : number of teeth, durability of the material to be used and also the width ( how wide the clip can open )

Advantages : very easy to use, holds hairs tight

Disadvantages : Expensive and material used is sometimes brittle

paper clips : This used to hold papers together it is made of a thin elastic wire

The design parameters to be considered are : length of the wire, material to be used and the elasticity of the material

advantages : it is quite cheap and good strength

disadvantages :it can hold a limited amount of papers together

potato chip bag clips: These clips are used on potato chip bags to ensure that the bags are air tight

The design parameters to be considered are : Elasticity of the material to be used , and size

Advantages : it helps to prevent the potato chips from getting exposed to air

disadvantages : Not very popular and its quite expensive

Calculate the density of a hydraulic oil in units of kg/m^3 knowing that the density is 1.74 slugs/ft^3. Then, calculate the spe

Amanda [17]

Answer:

Density of oil will be 897.292 kg $m^3$

And specific gravity of oil will be 0.897

Explanation:

We have given density of oil is 1.74 slugs/ $ft^3$

We have to convert this slugs/ $ft^3$ into kg/ $m^3$

We know that 1 slugs = 14.5939 kg

So 1.74 slug = 1.74×14.5939 = 25.3933 kg

And 1 cubic feet = 0.0283 cubic meter

So $1.74slug/ft^3=\frac{1.74\times 14.5939kg}{0.0283m^3}=897.292kg/m^3$

Now we have to calculate specific gravity it is the ratio of density of oil and density of water

We know that density of water = 1000 kg/ $m^3$

So specific gravity of water $=\frac{897.292}{1000}=0.897$

Which is a feedback mechanism for a system?

stira [4]

The following is a feedback mechanism for a system :

<u>The progress bar when downloading a file on iTunes</u>

<u></u>

Explanation:

A feedback mechanism is a loop system wherein the system responds to a perturbation. The response may be in the same direction (as in positive feedback) or in the opposite direction (as in negative feedback).
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.
Evaluation feedback needs to be done “in the moment” to help the person receiving the feedback know where they stand.
A feedback control system consists of five basic components: (1) input, (2) process being controlled, (3) output, (4) sensing elements, and (5) controller and actuating devices.
Because negative feedback produces stable circuit responses, improves stability and increases the operating bandwidth of a given system, the majority of all control and feedback systems is degenerative reducing the effects of the gain.
