The fouling on the heat exchanger surfaces causes additional thermal resistance, thus decreases the heat transfer rate. a)- True

b)-False

Answer:

True

Explanation:

First, it must be known that heat transfer is equal to the temperature difference divided in the thermal resistance, so the fouling that is a layer of dirt that accumulates on the surface of the heat exchanger over time this layer ends up becoming an additional thermal resistance, increasing the total thermal resistance, giving a drop in the rate which the heat is transferred, so in this case the statement would be true.

According to the
zysi [14]

Answer:

The part of the system that is considered the resistance force is;

B

Explanation:

The simple machine is a system of pulley  that has two pulleys

The effort, which is the input force at A gives the value of the tension at C and  D which are used to lift the load B

Therefore, we have;

A = C = D

B = C + D = C + C = 2·C

∴ C = B/2

We have;

C = B/2 = A

Therefore, with the pulley only a force, A equivalent to half the weight, B, of the load is required to lift the load, B

The resistance force is the constant force in the system that that requires an input force to overcome in order for work to be done

It is the force acting to oppose the sum of the other forces system, such as a force acting in opposition to an input force

Therefore, the resistance force is the load force, B, for which the input force, A, is required in order for the load to be lifted.

What is software certification? Discuss its importance in the changing scenario of software industry. ​
bekas [8.4K]

The software industry is evolving, and software certification is crucial. ​Software certification is a digitally signed certificate that verifies the identification of an individual or company. ​

<h3>What is software certification?</h3>

A certificate, sometimes known as a digital certificate, is a special document that has been digitally signed and authenticates the identity of a person or business.

Its validity may be checked using public-key cryptography to make sure that the program or website you are accessing is reliable.

Software developers must demonstrate that their program executes the XBRL conformance suites successfully in order to be certified.

They must also supply extra test cases so that XBRL employees can test the program further. The validity of certification is one year, renewable yearly.

Hence the software industry is evolving, and software certification is crucial. ​

To learn more about the software certification refer;

Orlov [11]

Answer:

C.) determine the heat of a fire.

Explanation:

NIMS certifies individual skills against the national standards. The NIMS credentialing program requires that the candidate meet both performance and theory requirements. Both the performance and knowledge examinations are industry-designed and industry-piloted. There are 52 distinct NIMS skill certifications.

Would be much appreciated if someone could help with this will give brainiest.
Mashcka [7]

Answer:   both mm and inches on each dimension in a sketch (with the main dimension in one format and the other in brackets below it), in the way you can have dual dimensions shown when detailing an idw view.

personally think it would look a mess/cluttered with even more text all over the sketch environment, but everyone's differenent.

If it's any help - you know you can enter dimensions in either format?  If you're working in mm you can still dimension a line and type "2in" and vice-versa.  Probably know this already, but no harm saying it, just in case.

You can enter the units directly in or mm and Inventor will convert to current document settings (which  you can change - maybe someone can come up with a simple toggle icon to toggle the document settings).  Tools>Document Settings>Units

Unlike SolidWorks when you edit the dimension the original entry shows in the dialog box so it makes it easy to keep track of different units even if they aren't always displayed.  (SWx does the conversion or equation and then that is what you get.)

I work quite a bit in inch and metric and combination (ex metric frame motor on inch machine) and it doesn't seem to be a real difficulty to me.

Match the benefit of full synthetic oil with engine conditions: All engines exhibit wear over time.
Lyrx [107]

Answer:

Inside the following section, certain advantages or perhaps the benefits of full synthetic oil are listed.

Explanation:

  • There seem to be a variety of possible reasons why it would be safer for synthetic oil. Even though synthetic oil becomes largely man-made, there's also a lot of fantastic monitoring over all of the chemical or oil composition.
  • This would have additional advantages for your engine because synthetic oil could be combined with various additives to improve the performance as well as sanitation of each fuel.
