Megan Lewis (BSE in Astronautics, 25) solves a pipe flow problem using the energy equation. The major and minor head losses are included, and reading the Moody chart is explained. 00:08:21 Reynolds number definition should use V, not V square.
Please note that students currently taking MAE 242 Intro to Fluid Mechanics at Arizona State University should use these video resources as references only, rather than substitutes for our course materials. These videos are created voluntarily by the former students who took MAE 242, not by the instructors, hoping that their understanding and knowledge of course materials can benefit future students taking the same course. Thus, the current instructors cannot be responsible for any inaccuracy or misunderstanding related to the videos, and one should use these resources at its own discretion.

Very helpful, but I got lost in the conceptualization without units.

How we can know which velocity to use when calculating major losses and minor losses?

when doing calculations for major and minor losses you want the average velocity within the pipe, since in fully developed flow the velocity profile is parabolic the best way to find the average velocity is to use the flow rate. Q = VA , so V = Q/A

@@garrettcrouch2086 what if i have 2 different pipe sizes which are, 12 inches and 3 inches at the beginning of the node. 12 inches being the water line header and flowing into 3 inches pipe to my designated equipment. The only known flowrate is only at the 12" header. Obviously, the velocity differs from each other. Which velocity should I use and why? Please help

Renolds formula is v not v squared😊

Thanks for finding that out. The error was already noted in the video description.
