Love the static pressure taps and pitot tubes shown at the end! It really ties things together :)

[@CPPMechEngTutorials]

And it's all true!

[@united3689]

@@CPPMechEngTutorials i actually dont understand how the two tubes are different, and how they would actually record different readings? Any vids on that?

[@janesydney7542]

Excellent explanation and graphics. Thank you so much.

[@omarwameedh191]

Hi, as i have taught the head losses of pump when put to the right of equ we give it negative sign whereas( hL) and (hT) have positive sign as they put on the right of equ... thank you for the great video and good job hope you continue to uploading more vids..

[@CPPMechEngTutorials]

As long as the signs are consistent, you can put any term on either side of the equation.

[@kevinbi3746]

Fantastic and brilliant explanation! I genuinely appreciate it!!!!!

[@CPPMechEngTutorials]

Thanks for the feedback.

[@zeeshanahmed9719]

Beautiful explanation, I was searching for exactly this video.

[@CPPMechEngTutorials]

Glad you found it!

[@zeeshanahmed9719]

Thank you very much.

[@CPPMechEngTutorials]

No problem.

[@luisleon8095]

such an exellent video! keep it up.

[@CPPMechEngTutorials]

We will. :)

[@likondwa]

thank you so much for this video, it simplifies everything.

[@CPPMechEngTutorials]

No problem.

[@joaquinruggeri4277]

Beautiful video. Keep up the good work

[@CPPMechEngTutorials]

Will do!

[@mohamedthasneem7327]

Excellent explanation !!!

[@CPPMechEngTutorials]

Thanks!!

[@petrichorcpb]

It's easy to understand,thnks!!

[@ahmaddiyar1536]

Love it nd it's our assignment task today

[@omercivileng9046]

what holistic vedio .... good bless you ... nonetheless, I have a question, what does turbine in the system mean ?

[@py2396]

Amazing video!

[@Chouby3]

great video mate i appreciate it :) helped me clear up some things

[@CPPMechEngTutorials]

Great!

[@angadkadampatil1206]

Thanks, Useful information, Exams Ahead...🙏

[@CPPMechEngTutorials]

Good luck!

[@abdulkaderfaisal1388]

Nice video. All in one

[@lumingunasinghe6008]

Why didnt egl change when flowing through higher to lower diameter ?

[@pauliusvainoras7787]

Pressure decreased -> velocity increased

[@rezhaadriantanuharja3389]

9 months later. If there are no energy gains or losses, EGL does not descend nor ascend. If there are no velocity changes, HGL remains parallel to EGL.

[@liamcope-ontariorealtor3576]

This was so helpful!

[@CPPMechEngTutorials]

Hooray!

[@shaileshtiwari6023]

Explained nicely

[@zaproud]

Awesome , Thanks so much

[@newachan961]

Thank you!!!

[@mekoandlibby9413]

I love this video so much. Thank you

[@CPPMechEngTutorials]

Spread the love around.

[@saitejachindanuru7313]

clarified our doubts...thanq soo much...

[@giteshkhanna2633]

Easy explanation! Thanks!

[@CPPMechEngTutorials]

You're welcome!

[@el3aou13]

Is gravirty g not missing below p in the formel ? Egl= p/gy + v2/2*g+z. Hgl= p/gy+z

[@CPPMechEngTutorials]

The specific weight (gamma) is equal to density times g.

[@el3aou13]

+CPPMechEngTutorials thanks for the clarification

[@CPPMechEngTutorials]

No problem.

[@evelynmh24]

Thank you for the video, it was very helpful and graphic.

[@CPPMechEngTutorials]

Glad it helped. EGL and HGL are nice ways to visualize energy, a concept that is very abstract.

[@daifukumochi3686]

Thanks 😊

[@chrishamel3001]

Fantastic video. Short, concise and clear. The static tubes for measuring the HGL, are those also know as piezometers?

[@CPPMechEngTutorials]

Yes, that can be called piezometers or piezometer tubes.

[@pvsmouli7727]

nice explanation easy to understand

[@CPPMechEngTutorials]

Glad it helped.

[@abdulkaderfaisal1388]

Thanks a lot

[@commandconquerfitness1506]

Good video, lot better than my prof

[@CPPMechEngTutorials]

Thanks

[@pandukabandararathnayaka7397]

so worth

[@unknownkom]

thanku mann its so much helpfull

[@CPPMechEngTutorials]

Great!

[@danielpapa5823]

well done

[@CPPMechEngTutorials]

Thank you.

[@gopalthakur3338]

I'm impressed with this video. thank you !!!

[@davidnavarrete4510]

essentially ... EGL & HGL are same same, but different. Just as confused after the video as before ahaha fml

[@CPPMechEngTutorials]

One has V^2/2g, the other does not.

[@dazai9035]

Good one👍

[@CPPMechEngTutorials]

Thanks
