Continuity Equation

098 - Continuity Equation

In this video Paul Andersen explains how the continuity equation is an application of conservation of matter in a fluid. The continuity equation may apply to either mass or volumetric flow. Example problem and examples are included.

I just wanted to share my thanks for making these videos.

I got a 5 in AP Bio and an A both semesters last year - thanks to you! This year I've gone through all your AP chem exams, and you teach much more in one hour than my teacher does in one week. Sometimes I wonder if you feel like you're helping us - YOU ARE! Keep doing what you're doing!

[nizra]

Mr Anderson, YOU ARE AWESOME! Your videos are the reason that I did brilliantly in my exams. A big thank-you!

[headintheklauds]

how did you get from .0176625 =.00041527 to 43?

oh man u r superb u r explaining the formula and concept behind it instead just deriving the formula i like that so much thank u for the video

Hi, I tried measuring the flow rate from my hose with and without a nozzle and got considerably different answers. I filled a 16oz cup and timed it a with no nozzle it took only 3.5 sec to fill it and with the nozzle it took 13sec. Wouldn't this indicate different values for Q? Am I missing something? So if I wanted to calculate velocity of the fluid by using flow and area, which flow rate would I use? Thank you!

How to understanding this case, when we have reduced cross section in pipeline (caused by valve half closing) the time to fill up in a tank is different when I fully open the valve and half open, does this mean flow (Q) in faucet valve end is less than the source? Kindly explain, thanks

[sonnco]

I understand pressure and flow much better now because of your great video. Thank you!

Please help how did u get that answer at the end I've done all the substitution and swapped every iniger u can think of????😩

[joebopp]

In the simulation, why would the flux change if the amount going through is always the same?

[akij]

hi! great video. but what if the given dimensions on A1 has length, height, and width in meters, which will then have a unit of m³. while the A2 has a given area of m². V2 is given. how do you solve this? THANK YOU!:)

[johnpark]

Ever ever great clips worth spending time for not only one proof explanation but all related poisoneous videos, thanks

[emmanuelmtera]

very helpfull understandble video i am in a level taking physics studies thank you so much for your video it was really helpfull.

[sagartale]

Great video.. Thanks for the upload.. when a valve is present on pipeline and if it is closed partially then, does the flow rate still remains the same with change in velocity ?

[GirishManjunathMusic]

For the sample, couldn't we convert m/s into cm/s?
wouldn't that make it a bit easier?
Or is that wrong?
So many questions... :D

[nouraalkitbi]

Thank you for your lesson it was helpfull for me
