sTEm–at-Word Puzzle #61: Pump Part selection for thick fluid applications

Analysis: A new technician at a pump repair company is asked to rebuild positive displacement pumps for a customer that uses their pumps to transport viscous fluids.  The technician knows that for constant viscosity (constant thickness) fluids; a higher pump pressure applies a higher stress on the fluid; the Shear Rate of the fluid always increases linearly with Applied Stress; the fluid's Shear Rate value multiplied by the fluid's viscosity value always equals the Applied Stress value.  The tech knows this customer always uses their pumps to move a fluid that gets thinner when the pump applies more pressure on that moving fluid. The tech also reviews the graphic at the red and green data points and, even though there are no values provided on the ordinate (y-axis) or the abscissa (x-axis), is absolutely positive which Repair Kit to use. 
 
 
The Question : Does the Technician selects Repair Kit #450?  

 
YESor NO

Mechatronics Community Exchange Showcases TAMU Project

Image
The Mechatronics Community Exchange (MCE) is a group of   mechatronics educators in 2-year programs that meet virtually most months during the academic year.   On March 22, the MCE meeting showcased the an NSF ATE Mechatronics project at Texas A&M, College Station, Texas.   Dr. Tony Hsieh , Director of the Rockwell Automation Lab and member of the graduate faculty is the P.I. of the “Innovative Curriculum for Industrial Automation” or “ ICIA ” project (NSF DUE 1304843 ) . This project is supporting and creating innovative curriculum, lab exercises and pathways to increase the number of qualified technicians and engineers in the areas of operation, troubleshooting, design and integration of automated manufacturing systems (industrial automation). The curriculum pathways developed include a series of courses, lab exercises (hands-on, remote and virtual formats) and learning experiences that equip students for a successful career in automated systems and industrial...

Mechatronics and Vacuum Technology

Image
The terms Mechatronics and Vacuum Technology represent 20 th Century state-of-the-art “tags” for leading edge STEM based skill sets that are even more significant in this 21 st century digital world.   Mechatronics was coined in the 1960’s to verbalize the then brand new integration of mechanical and electronic knowledge for commercial (automobiles, etc), space (moon mission) and defense (ICB’s) applications.   Vacuum Technology could trace its heritage to the 19 th Century (Edison’s work with incandescent filaments for example) but certainly is anchored in technology development (radio and television) in the 1920’s and cemented in all advanced technologies triggered during and post Manhattan Project.   Although there is always a tendency to rebrand almost everything ( IHOP to IHOB for the latest example), new identifiers for either of these incredibly STEM based skill sets is not necessary.   What is important is to recognize that from a technician’s perspective...

  2018 Synapse Innovation Summit The 2018 Synapse Innovation Summit, designed to bring together organizations, innovating ideas and advanced hi-technologies from a wide range of industries and organizations to connect regionally-based innovation technology, education, and entrepreneurial ecosystems throughout Florida, was held at the Amalie Arena in Tampa, Florida. Created by the nonprofit Synapse, named for the link between nerve cells in the body, the second annual Innovation Summit included 15 hours of programs and 10 hours of learning, exploring and celebrating the possibilities in advanced hi-technology and innovation, to help connect and establish relationships among those who can contribute to the growth of the Tampa Bay entrepreneurial ecosystem.   There were 250 exhibitors, more than 60 showcases, 56 breakout sessions, 200 speakers, and 2,500 attendees who flooded into downtown Tampa’s Amalie Arena March 28 and 29. Highlights included “spotlight” sessions devo...
