Fluid Mechanics: Topic 6.1 - Systems vs Control Volumes

[@waleedkhan8590]

A very good explanation! One that gives you an intuitive sense for the 2 different approaches. Wished professors in college would teach these essential concepts as well

[@CPPMechEngTutorials]

Thanks! It takes a while to get used to the two approaches.

thanks

thanks....Great job

[@dhimanbhowmick4837]

good explanation

[@vridhikhanna1580]

Our professor told that in control volume the boundary will be fixed it will not change. But in your last example boundary changes as size of ballon shortened.
Any explanation please

[@CPPMechEngTutorials]

For many practical applications, the CV boundary is fixed relative to the observer. For example, a pump usually has a solid casing and is fixed to the ground. However, in general a CV can move about and grow/shrink.

awesome

[@fachrial_novri_triyandi4092]

do you have video problem solve for deforming control volume?

[@CPPMechEngTutorials]

Many fluid mechanics textbooks give an example of how to deal with that type of scenario.

Sir my college teacher saying
Control volume is open system
System is close system
And he also say that
System have fixed mass and only energy transfer take place
Whereas CV have fixed volume and mass& Energy transfer take place
Is it correct??

[@gillutv]

yes

Awesome...i understood 👌👌

[@CPPMechEngTutorials]

Great!
