Shockingly bad sound quality

thankyou so much sir,your videos are really helping me a lot😊. wishing you all the best 😇

Pease upload other lectures also sir 🙏🏻🙏🏻

Don't have words to describe the quality of lectures

These are really brilliant lectures

Greetings Sir. In this Playlist of C programming the audio in most of the videos gets echoed or sometimes very low. Even if we try to go with the max audio on our device the audio is still not clearly audible. Please can you do the suitable changes to make the audio clearer from your end

Very Informative 👌

You always made our learning easy sir whenever we found it difficult.

Thankyou sooo much , i was searching for it since 1 week , you nailed it , exactly what i want find

Really superb sir

super explanation sir

ive been looking for a course made by and for mechanical engineers for a long time. thank you for your time, effort and initiative mr. rankaj. much respect and love from turkey

Thank you for your videos Pankaj, they are very interesting.

Amazing content

Thank you!

best teacher

Nice explanation sir

at 5:12 there were three integrals in the volumetric integral due to integral along x, y and z directions?

Thank you so much sir

Can we go from one coordinate system to another, by using vector form, in case of acceleration and vorticity?

WORLD NEED SUCH TEACHERS. WELL EXPLAINED. YOU REALLY VERY INSPIRING PROF.

Sir how to use special symbols in Anaconda Spyder or IDLE python?

wow, you have made my day . i enjoyed it . thank you very much.

thanks a lot sir for this amazing lectures

رايق

Great playlist

Could you please upload part 2 and questions Awesome lectures..

Can you write here the last term of equation and described what it is mean please

awesome

thank you so much sir

Good sir 😃

Thanku sir ,very helpfull vedio ....

Thank you sir

Thank you so much. Been searching for integral form of continuity derivation.

sir,plz try to upload videos more frequently..
