Engineering 2C3 - Electricity, Thermophysics and Energy
This is the web page for Engineering 2C3 offered Jan-Apr / 2001.
It does not apply to the current offering of this course.
An exposure to electrical and thermophysics fundamentals having civil engineering
applications. Topics: electrostatics, electric currents, circuits and transients,
electrical power engineering, energy efficiency, heat transfer mechanisms.
Three lectures per week; second term
Prerequisite: Physics 1E3 and registration in Math 2M6
Lecturer: Bill Garland, ext 24925,
Teaching assistant: George Schwartz
Ongoing tutorials, typically on Thursdays. We'll do worked problems
in class, have discussions and, due to popular request, learn C programming:
2001.02.01 & 08: Numerical assignment: For the RLC series circuit
as per lecture notes page 33.5b, solve for i as a function of time
numerically. Give voltage drop across each component as well. Use
what ever language you wish. A spreadsheet will work fine. Show your
numerical procedure. Graph i and v as a function of time. Compare
the result to that found analytically in the notes, ie, compare Imax
and phase lead or lag. Discuss. This need not be handed in but you
can expect a question of this nature on the midterm and / or the final.
Bring you work to class on Thursday so you can work on it in groups.
2001.02.15: Before class, down load the C compiler from the Downloads
page if you don't have a C compiler already. I'll go over the setup
and use of the code in class.
2001.02.26: Here are my solution
(pdf 218kb), including:
A writeup on the solution procedure.
An Excel spreadsheet solution which I found it to be an obtuse
way to 'program'. I don't recommend it.
C code, written with Borland C++ Builder. You'll have to make
some mods to get it to run with Miracle C.
Output presentation using MathCad. The output file from the
C code is read in and plotted. You could use a spreadsheet instead.
Teaching matters - helpful general
information on teaching and learning for the student and the educator.
How Stuff Works - You can
find descriptions of how many electrical and thermal devices
work on this site. Don't expect much in the way of mathematical detail, however.
Elite Software - Over 30 programs
are offered for such applications as HVAC load calculations, building energy
analysis, HVAC duct and pipe sizing, plumbing & lighting design, fault current
calculations, voltage drops, fuse and breaker coordination, and much more.
Free demo versions available for download.
HVAC Software - Residential
heat loss / gain calculations. Free trial version available for download.
