Is it weird that for as long as I've worked with fluid flow in pipes, I've been fascinated by roughness? I was doing other things while watching this video, but at 7: 24 I couldn't help but perk up and pay more attention.
It so often makes such a small difference, but I always found myself wishing that there were more data out there covering roughness measurements! And I always had to caution my students that while tuning roughness to get your simulations to match measured pressure losses was a reasonable thing to do, you also had to take care that you kept it within reason. There are few things more frustrating than seeing someone -match- their simulation to measured pressure losses by increasing the roughness to a value greater than the inside radius of the pipe!

In a moving fluid energy is conserved
As the speed of a fluid flowing horizontally increases, the pressure drop will decrease is Bernoulli's Principle
An isentropic flow both B and C
Bernoulli's principle only applies to horizontal flow so as to not take into account gravity
The resistance of two things sliding against each other is friction
Everything happening inside a system is called a process
The _______ the velocity of a fluid, the ________ the frictional losses greater; greater
What country was Bernoulli from? Switzerland
Who was jealous of Daniel Bernoulli? his father
All of the following are fluids EXCEPT rock
be back next time stay fresh kings

I may be nitpicking a bit here, but your definition of Bernoulli's Principle seems poorly worded. It should read: -As the speed of a fluid flowing horizontally increases, the pressure will decrease. - the term pressure drop describes the change in total pressure between two points in a network. As the speed of a fluid increases, the pressure drop between two points will actually increase.

So everyone is talking about pop culture while I'm thinking about where to apply this to my video game. I've also taken into account most of the concepts in physics as well as those presented in this series. See me in like 2-4 years when I make substantial progress on that, and simulate reality (or alter it a bit)

This is like using barometers and other weather gadgets so help us God, that we may design buildings that won't melt in the heat, I can't wait to hear about to new data in Sept. or December in 2018 this year. I like the pump idea's like septic shark, or being able to pump out the septic tank: -)

Thank you for this incredibly well thought out prsentation. The framing in your wideshot is terrible and distracting. Please research and apply the concepts of -head room- and -rule of thirds- in future videos. And thanks again for presenting these concepts.

I zoned out like one minute in. ------
BTW, it's pretty discouraging to see such a messed up shelf behind her considering this is a subject on physics. -

No mention of Moody diagram/chart! In my opinion, still one of the oddest (but very useful) empirical tests ever performed.
