Thermodynamics( Heat Transfer ,Due Within 3 Hours

 1. A thin flat plate is positioned in an air flow of 30 m s-1 . The length of the plate in the direction of the flow is 1.0 m. The width of the plate is 0.5 m. The air temperature is 20 oC. The plate temperature is maintained at 80 oC. Determine the heat transfer rate from the plate if: a) the leading edge is smooth (10 marks) b) the leading edge is rough (10 marks)  2. An air duct heater consists of an aligned array of electrical heating elements in which the longitudinal and transverse pitches are SL =25 mm, ST = 25 mm. There are 5 rows of elements in the flow direction (NL = 5) and 4 elements per row (NT = 4). Atmospheric air with an upstream velocity of 10 m s-1 and a temperature of 25C moves in cross flow over the elements, which have a diameter of 12 mm, a length of 250 mm and they are maintained at a surface temperature of 300C.  Determine: a) the air-side heat transfer coefficient (8 marks) b) the total rate of heat transfer (6 marks) c) the temperature

Renewable energy project in mining industry

Topic is Renewable energy project in mining industry, but you should write some of the next options.
-solar gas-battery hybrid or solar-wind diesel hybrid.

The essay should include a presentation and conclusions.
Part of the essay should be about mining and its impact on the environment and global warming.
The second part should include their achievable benefits, price, Enviroment, efficiency.
The last section should briefly describe the new planned projects and projects already under construction and their schedules.

I need also a very good and quite new sources about (10-15)

Short Paper The Digital Divide

 

As we have experienced, the Internet and its related technologies has  a dramatic impact on the nature and quality of our lives. As Internet  users, we have vast amounts of information literally at our fingertips.  We can communicate, collaborate, and transact on a global scale in ways  that were unimaginable only a few years ago. But even in a society as  technologically advanced as we are, there are still a large number of  those that do not have access to this technology, dont have the skills  to use it or refuse to utilize technology for other reasons. As you  approach this assignment, think of those affected by the Digital Divide  more broadly than the traditional angle of who has and who has not.

After reading the module notes and all supplemental materials, respond to following:

  • Briefly describe the traditional definition of the digital divide. What is it and who is affected, positively and adve

How Has The Use Of Technology Affected Peoples Ability To Communicate Face To Face?

 

Technological advancement in the last century has had a drastic  impact on the way individuals communicate. The introduction of  ever-progressing cell phone technology, personal computers, and social  media has enabled increased control over our personal interactions with  each other and is playing a large part in the shifting of social values  and priorities. As communications technologies continue to advance ever  further, it calls to question whether the shift in communications is a  good thing or a bad thing and whether technology is aiding or hurting  personal relationships.

After reading the module notes and all of the supplemental materials, respond to the following:

  • How has the use of technology affected peoples ability to communicate face to face?
  • Do you think that the mere presence of technology, such as in the  form of smart phones, affects peoples ability to communicate with  

Reply To The Following Post Below

 

As we look around us, we can see how much technology places an impact  in our lives.  There are a few jobs that have already been replaced or  are starting to be replaced right before us.  One of the jobs is a  cashier at a grocery store being replaced self check out.  I know that  at times, especially with the younger generation, there is a preference  to check items out independently and avoid social interaction, rather  than go to a cashier, and therefore the rise in self checkouts make  cause the elimination of the cashier.  Another cashier role that could  be gone in the next few years, is the cashier at fast food restaurants.   There has already been a movement of self checkouts at these  establishments as well. Along with these jobs, really anything that  involves repetitive motions is up for grabs by some sort of automation  technology, because robots are cheaper , faster,

Leak Detection Methods – Reviewing a research paper

I have a research paper that includes multiple methods in leak detection. For methods 3, 4, 5, 6, 7, and 8 (2 and 9 excluded), I require a brief summary about them. No introduction or conclusion is needed. Only a brief 2 or three sentences explaining the method used, and if available, the results of that method.

Frame Aggregation and MU-MIMO Mechanisms in Next Generation Wi-Fi Networks

a report including an objective , ethics and research about Frame Aggregation and MU-MIMO Mechanisms in Next Generation Wi-Fi Networks mostly focusing on the ( 802.11ac ) 
To investigate the use of frame aggregation and MU-MIMO mechanisms to improve channel utilization in next generation IEEE 802.11ac networks

wind data analysis using matlab and excel

the report should include and introduction ( objectives ) , ethics and research

the excel sheet has all the information needed.
while the word document is the aim of the project. don't focus on the entire aim just focus on the topics listed above ( introduction , ethics and research )

Let's use 2003 initially - it has the smallest standard deviation.
Introduction could include:

a description of what you hope to achieve by carrying out the data analysis
a description of the site - with a screenshot from Google Maps if possible
a description of the data - sampling intervals, data collected, etc.
(we'll revisit the data - we'll carry out a "sanity check" on the data to make sure it's reasonable data rather than simply using it on trust)
why you rejected 2006
why you selected 2003
a graph showing weekly average wind speed for 2000-2005
a graph showing weekly average wind speed for 2003
...anything else that you think would be interesting
