Director, Wind Energy Research and Commercialization (WERC) Center
Director, Wind Energy Section, Great Lakes Energy institute ENGR 225. Thermodynamics, Fluid Dynamics, Heat and Mass Transfer (4)
Elementary thermodynamic concepts: first and second laws, and equilibrium. Basic fluid
dynamics, heat transfer, and mass transfer: microscopic and macroscopic perspectives. Prereq:
CHEM 111, ENGR 145, and PHYS 121. Coreq: MATH 223. •Course Description
•Why are we here?
•A little history of our profession
•Yours Characteristics of Engineers
5. Strive for efficiency
Design for labor-saving systems
Design control into the system
Favor the very large, the very powerful –or- in electronics – the very small
Treat engineering as a means to improve the human condition What is the etymology of the word Engineer?
Latin – ingenium - clever solution in a mechanical sense
Ingenuity – cleverness in devising
Ingenious – cleverness in conception or execution
Engine – a mechanical tool, as in an engine of war
French – engineer
1676 – officieurs des corps du genie (Louis XIV)
1716 – corps des ponts et chaussess (Louis XV)
1795 – Ecole Polytechnique (Napolean - meritocracy)
Theory -> Application
4 years of education (3 years common core, 1 year specialization)
1st Engineering School in the U.S. – West Point 1817
How do you tell the difference between an Engineer and a Scientist? So you are a __________ Engineer
Given that the second word in your title is Engineer –what should you know?
(and who decides?)
The faculty of CSE (about 110 souls) assume an average of 30 years experience
(or 3,300 years experience –or- 165 generations of experience)
The faculty of CSE have debated and voted that you should know:
1. ENGR 131 – Elementary Computer Programming
2. ENGR 145 - Chemistry of Materials
3. ENGR 200 – Statics and Strength of Materials
4. ENGR 210 – Introduction to Circuits and Instrumentation
5. ENGR 225 - Thermodynamics, Fluid Dynamics, Heat and Mass Transport let’s talk about work •20 years/generation
•50 generations/1,000 years
•12,500 generations/250,000 years A quad is a million billion BTUs Course Goals Florence, 14th Century painting Florence, 16th Century Painting Knowledge is a human-made artifact.
When your views of reality are changed by knowledge,
Reality itself changes.
That is the day the universe changed for you. epistemology – metaphysical subjectivism – cogito ergo sum ...
