Great lecture! At 2:52 I think we should look for 0.003 instead of 0.03 on chart, if I'm not wrong.

He did look for 0.003 on the map. :) Just a slip of tongue

What if we are given the friction instead, how would you find the relative roughness or at least the roughness of a pipe using experimental data only?

What if the flow is laminar.. could you tell me what is the next step..?

Great explanation! I was following all the way through. I just need to know what "effective length" is. Apparently it has the something to do with the addition of head loss in pipe and head loss due to fittings (k factor)? Any help would be greatly appreciated!
@MichelvanBiezen Жыл бұрын
The effective length is the length of a pipe that would account for the same pressure drop or head loss as the pipe in question without any bends, fittings, etc.

@Michel van Biezen how are you doing? I was wondering if I can ask you a question, regarding head loss math problem I have. I can't seem to figure it out. Can I email you ?

where can use the formula 4flv^2/2gD and flv^2 / 2gD is there any difference? please give some example between 4flv^2 /2gD and flv^2 / 2gD . when I can use that formula?

I know this is not really relevant to the video exactly but does the viscosity of a fluid depend on its temperature if so what formulae are there to describe this, also does the flow rate change therefore depending on temperature?
@MichelvanBiezen5 жыл бұрын
Yes, they are both dependent on temperature

Why does my book and teach say RPR is D/e I noticed that a lot of formulas we’re using on my class are kinda swapped, like that, idk why. Our flow graph relative roughness numbers are the polar opposite, they’re tens of thousands as opposed to 10’s of thousandths.

Mr. Michel why did you calculate the friction factor from the Moody diagram? Could I possibly have utilized f = 64/Re where Re is the Reynolds number I solved using that and my answer appears to be encountering a momentous deviation from your answer 😭
@l0kesh_a5 ай бұрын
64/Re is for when the flow is laminar. If Re is more than 4000, its turbulent and u need to do with moody

where can use the formula 4fLv²/2gD and flv²/2gd is there any difference? thank you sir!😊
@MichelvanBiezen Жыл бұрын
The Darcy Weisbach equation for frictional head loss is: flv^2 / 2gd.

Dear, Michel van Biezen. It was a wonderful tutorial. Appreciated it, Thank you! But, How about pipes connected end to end? or a network of supply lines going to the house tap, say, a shower?
@MichelvanBiezen4 жыл бұрын
Yes, what we typically cover is the theoretical pipe flow without viscosity and affect of bending and connections. That requires a whole new set of videos covering those topics. We plan on covering that, we just haven't been able to get to it.
