Article: Shell and tube heat exchanger

'''Is everything in the article relevant to the article topic? Is there anything that distracted you?'''

Yes, the article is relevant to the topic.

'''Is the article neutral? Are there any claims, or frames, that appear heavily biased toward a particular position?'''

The article has a tone of neutrality throughout.

Are there viewpoints that are overrepresented, or underrepresented?

The uses of the shell and tube heat exchanger are focused on power plants and how it is used in that particular industry. However, the food industry's uses are not mentioned. Therefore, the article should contain a section that highlights its use in food manufacturing plants.

'''Check a few citations. Do the links work? Does the source support the claims in the article?'''

Yes the links work and most of the references are websites of companies manufacturing this type or other types of heat exchangers.

'''Is each fact referenced with an appropriate, reliable reference? Where does the information come from? Are these neutral sources? If biased, is that bias noted?'''

The 'Theory and Application' section and first part of the 'Shell and tube heat exchanger design' section contains no references. Additionally, the diagrams of the different designs of the shell and tube heat exchanger and the explanations are great, but, they do not have any citations. The information is taken from company websites that manufacture this type of heat exchanger but the sources talk about the heat exchanger's application and its process flow.

'''Is any information out of date? Is anything missing that could be added?'''

The uses of this heat exchanger in food and beverage manufacturing can be added.

'''Check out the Talk page of the article. What kinds of conversations, if any, are going on behind the scenes about how to represent this topic?'''

The Talk page contains a question that wants to know a specific detail about the manufacturing of this heat exchanger while another user has suggestions that can improve specific sentences and general sections of the article.

'''How is the article rated? Is it a part of any WikiProjects?'''

The article has been rated as Start-class with Low-importance on the WikiProject Chemical and Bio Engineering. On the WikiProject Technology it is rated C-class.

How does the way Wikipedia discusses this topic differ from the way we've talked about it in class?

In class, we learned that shell and tube heat exchangers can be used for low-viscosity foods that do or do not contain particulates. On the other hand, Wikipedia focuses on how the heat exchanger is used in power plants and for hydraulic fluids and transmission.
