Fluid Mechanics: Topic 7.1 - Conservation of mass for a control volume

[@Fraidoon]

You just explained all this in 9 minutes, while my professor explained in 2 hour long video. I can proudly say, i learned more from this. Thank you!

[@CPPMechEngTutorials]

It took us much longer than 2 hours to write, record, and edit the video. :)

[@Fraidoon]

You guys are awesome! @@CPPMechEngTutorials

[@MrMarkgyuro]

I study physics on my own. Your videos are so powerful and helps me so much! Thank you!

[@flashman654]

Wonderful explanation. These videos are very informative!

[@CPPMechEngTutorials]

Hooray!

[@kejserrige]

I couldn't thank you enough for this video. So consise and very well put-together. Thank you so much sir

[@seyedmohammadhhojatzadeh8337]

I did not breath for 9 min! Unbelievable explanation

[@CPPMechEngTutorials]

You were only 15 minutes short of the world record.

[@NAYAN-t3e]

From the video, whatever I've learned that is writing - 1. For steady flow, there is no net accumulation of mass with the control volume provided that the control volume it self should not be deforming in the time scale of instants considered. 2. In steady flow at any instant in time, the incoming & outgoing mass fluxes are same so that the mass content at any instant in control volume remains the same.

[@Air_reels]

Thank you very much for the videos. They're extremely helpful and have cleared up a lot of confusion.

[@CPPMechEngTutorials]

We're glad they've helped people.

[@AceofDlamonds]

You sir have helped me a bunch with just this one video! Im watching the other fluid dynamics/mechanics of mat. right away!

[@CPPMechEngTutorials]

:)

[@bola5671]

I sometimes wonder why I even go to class when I have you to break it down. I don't even need the textbook if not for questions that may come out on test to practice ahead of time

[@cakefactoryy]

Phenomenal video man, thank you so much!👍

[@lidyamelkamu5111]

what about for control mass or closed system?

[@ahmarmirza7720]

Differentiate between “conservation of mass” and “conservation of volume”. Under what conditions they become identical? In a compressor, whether both or anyone (which) is valid?

[@Joe-nl4vf]

im confused on what is the main difference between mass and linear conservation, can u explain please?

[@omaralani1105]

Can I ask how you typed the symbol for volume on ppt? I am not able to.

[@CPPMechEngTutorials]

V with a strikethrough.

[@Frank_The_Tank22]

At 3:08, it was stated that with steady flow, the term with the time derivative will equal 0 and because of this, the second term will also equal 0. However, on the next slide, we begin analyzing a steady flow device and acquire different results. Can you please clarify how this happened?

[@CPPMechEngTutorials]

We use the steady state equation as the starting point to analyze the generic device. What do you mean by "acquire different results?"

[@adamalmuhana7410]

This was a really good video thank you

[@anthonykyang89]

I didn't understand where the walls part came from. Can you explain it a little?

[@CPPMechEngTutorials]

What part of the video are you referring to?

[@anthonykyang89]

@4:45 the wall of the integral.

[@CPPMechEngTutorials]

The control volume consists of both the entrances and exits, as well as the walls of the device. The area is broken up into the five inlets/outlets, and the remaining area which is the walls.

You are always great! Thank you. 🖤
