into MAE 3140 Heat & Mass
Those marked with an asterisk (*) mean
that you can do it with appropriate references available – others to be done
able to take any well-posed, “word” problem and state what is given
(input) and what is unknown (output).
able to draw a control volume appropriate to the problem at hand and
identify what physical quantity/mechanisms must be considered and/or
able to work easily in both SI and English units.
savvy enough to recognize hints as to what you can be expected to know on exams
and later – e.g., coverage of the same topic multiple times in lecture,
workshop or homework.
able to work collaboratively such that you learn more than what you would have
learned working on your own – not less.
willing to ask questions and participate in class.
