Physics 34.1 Bernoulli's Equation & Flow in Pipes (7 of 38) Relative Pipe Roughness

In this video I will calculate relative pipe roughnesss and explain a chart of the constant of some typical pipe materials of coarse/smooth concrete, drawn tubing, glass, plastic...

Good demonstration of confirming proper units. Recommend always including units when writing equations.

Thanks for the video! You should mention that the answer to the video is located in the previous video, because in this video we don't get what the friction factor is!

Amazing explanation 👏 👌 everything clear. Thank you so much. Very useful. God bless you and I really appreciate you sir 🌹🌹🌹

D is should internal diameter of the pipe.hence the valve should be less than 6”

can i ask where did you get the table of constant permittivity's shown

is the Iron Cast Pipe roughness is 0.26mm?

Sir could you plzzz make a video on multipole expansions in electrodynamics i am not saying for the mathematical stuff just only for intuition real meaning of multipole bcouse i am bit confused how a simple continuous charge distribution can behave as dipoles and quardupole when observed by large distances ???
