Unit analysis (and unit errors)

Показать описание
Unit errors come in many different flavours on my exams. Sometimes they are simply signs of a momentary lapse of reason, like translating 10 minutes to 1/6 seconds. Other times I suspect there are deeper misconceptions behind the unit errors. In this video I try to into depth regarding units and unit analysis. I hope this video helps someone out there to get less points deducted on an exam.

Some examples are taken from my courses

KETF40 Mass Transfer in Environmental Engineering and
KETF10 Separation Processes

but the entire video is rather general in nature.
