-I feel like the series has been a little more practical lately instead of being just Engineering Physics. That's good. -
-Engineering is still a very broad topic, though. Sort of like taking Crash Course Literature, Crash Course Film, and Crash Course Theater and then condensing them into a single series called -Crash Course: The Arts. - Or at least part of a series. There would still need to be room for Music and non-performance visual arts. -

Instead of parallel flow and counterflow, I learned them as co-current flow and counter-current flow. (They might not have been hyphenated--it's been a while and I don't have my old textbooks handy to check) This is a great refresher for me, although it brought back terrible memories of trying to calculate temperature changes across shell-and-tube heat exchangers. :-)

-_. why don't laundromats have multi-plate heat exchangers on their dryers and washers- there's even a sense of all-climate operation to it: independent of ambient temperature. (also, ultimately you'd want to discuss air-flow-pressure heat-transfer-rate, 'efficiency'. (also, please, discuss 'heat pumps' and their, efficiencies and advantages. _-

there is an experimental radiator design called liquid droplet radiator. Where at one end it atomize the heat transfer fluid into very minuscule droplets with extremely high surface to volume ratio in order to maximize heat transfer. Then a collector at the other end recycle the droplets.

Hmm introducing the simplified Formula in 5: 01 and then saying finned tubes increase the heat transmitting surface is at best missleading.
Due to this and other issues i am sorry but i have to say that the script of the show was a little sloppy.

I appreciate your simplified explanation about heat exchangers and fluid mechanics. It's like summarizing the keypoints of chapters 5 and 6 of Perry's Chemical Engineers Handbook. Keep it up engineer. ;)

But in all of those heat exchanges the cold fluid warms up. So if you need tot get that cold by an other heat exchange than u keep going. So how do you keep the cold fluid cold?

You can work and research heat exchange systems following the career of Mechanical or Chemical Engineering (the first sizes and constructs, the second only sizes.

The first and last type of exchangers are literally the same thing. The shell in tube thing is just lots of inner tubes and one big outside tube.

The best way to re-heat a pizza is by using a frying pan. For initial preparing obviously an oven is best. Using a microwave gets you a saggy pizza
