engineering calculations for the nuMI PROJECT WATER SYSTEMS
August 10, 2001
The Neutrinos at the Main Injector (NuMI) project requires the installation of complicated electric devices and machinery that need to be water-cooled. This report is composed of two projects. The goal of the first project is the design of a stand for a large shell and tube heat exchanger, which will be used for NuMI. The second project primary goal is to size up the pumps needed for the absorber raw system, which is the water system that cools the absorber. Moreover, the second project had more implications than just choosing the right pump; many other components of the water systems had to be chosen according the demands of the systems. This report has two main purposes. The first is to describe the train of reasoning followed to solve these engineering problems. The second is to present the results obtained.
The two parts of this report are listed below; they may be accessed by clicking on their name. All these web pages work better with later versions of Internet Explorer.
Part 1 - MI-62 Heat Exchanger Stand
Part 2 - NuMI Absorber Raw System
Many of the calculations for these two projects were done in Scientific Workplace. They could not be included in the report because they were made in a different program, so they had to be converted into the PDF format. Therefore, Adobe Acrobat or other pdf reader is needed to view these files. Links to the pertinent appendixes are located within the text of the reports. The appendixes can also be accessed here. Clicking on any appendix will open a new window. However, if the appendix takes a long time to load, try saving the file into your hard drive and then open it with Adobe Acrobat.
Appendixes related to the MI-62 Heat Exchanger Stand project.
1. Appendix I, detailed hand sketches of the heat exchanger stand.
2. Appendix II, Scientific Workplace solutions to the two free-body diagrams.
3. Appendix III, calculation to obtain the radius of curvature of 4X4, 5/16” steel columns.
4. Appendix IV, calculation on the flexural stress of the base plates.
Appendixes related the NuMI Absorber Raw System.
5. Appendix V, formulas used to obtain flow rates across the absorber plates.
6. Appendix VI, spreadsheet solution to the formulas obtained above.
7. Appendix VII, specification sheet for the plate-and-frame heat exchanger.
8. Appendix VIII, specification sheet for the shell-and-tube heat exchanger.

This was a really great summer for me. Not only I was able to apply what I had learned in the classroom, but I also got exposed to the more intricate aspects of engineering. Those things one does not learn in school. I was also able to attend the conferences given by great scientists at Fermilab, including Nobel Prize winner Dr. Lederman. I gained knowledge of some of the work dynamics and culture of this fantastic Lab and I was able to visit many museums in Chicago. I owe all this to the SIST program.
I would like to thank Dianne Engram, Dr. McCrory, and all the personnel that made this program possible. I would like to also thank all the UTEP faculty and staff who helped me greatly to achieve my goal. My special thanks to Dr. Davenport for his help on my paper. Thanks to all the SIST participants, for the good times we spent together; my family and girlfriend, from whom I never lacked support. Finally, all my gratitude to my supervisor Dave Pushka, who with patience and dedication taught me some of the engineering of the “real world”.
