Dear NPTEL thank you so much for these lectures. These lectures are one of the best. Please improve on quality of video (720p or at least clear 480p). Sometimes we can't read the words written on page by sir.
Amazing lecture. Very excited for this series. Thank you Professor Som and nptelhrd for sharing this knowledge. I do have a question though: at 47:05 you said E=T*w, shouldn't this be E=T*theta? Nvm, got it, you defined E as rate of energy transfer.
There is a very trivial doubt I have, Please anyone answer it, The Euler Turbine equation developed here is valid because u1 = u2 = u Howsoever, If u1 is not equal to u2, The equation would fail, as per the proof shown here. So, why then, is this applied to steam turbines or centrifugal compressors.
@@mech-www7563 I have figured it out in my course of time. The Force calculated here by use of changes in relative velocity is valid only for some cases. However, the force is actually calculated by difference of absolute velocities and not relative velocites. So if you were to calculated force by use of absolute velocities only, you will always get the right answer. Only rocket is an exception to it, due to a different mechanism prevailing in it.

Iam so grateful to you sir.and i remember you till my last breathe.
very good teacher i learnt whole fluid from this teacher salute.
These lectures are very helpful.. thanks..
Thnks nptel and pro. S. K. Som
nodoubtat all "Prof. S. K. Som is the best of all."
Thanks Master! You are a incredible teacher 🤓
all the lectures are very helpful.

E is energy per second. Not energy
thank you sir so much for meticulous explanation
For anyone annoyed by the right channel audio: turn mono audio on in your computer settings
mujhe laga earphone gaya
your lecture is very helpful for us thank you sir..........
Sir thank you for help us...god bless you sir
Ty very much sir
God Level
very useful for me.. thanks
Thank you so much...
many thanks...
Is this video About fluid mechanics 2?
Can anyone explain me 47:37 how w is converted into u2 and u1
Is this playlist about fluid mechanics 2?
has anyone prepared notes from these lecture series? if yes, please share.
at 4:16 someone has coughed . if it was 2020, the class would have been stopped.
36:31 how Vr1 cosb1=Vw1?
Answer is given @38
It is not,
Vane velocity, u, cancels out
(V_w1 - u) + (.....
Nvm he explained it
Which textbook?
in which year he made this lecture series
There is a very trivial doubt I have,

Howsoever, If u1 is not equal to u2, The equation would fail, as per the proof shown here.

I too want to know th e answer for that...
But in impulse turbine U1 and u2 will be cancelled out but in reaction turbine it was not

Thank you dude
thank u so much sir,,,
im interested to learn this in the future, what is the prerequisite for the subject, is fluid mechanics already enough?
i would say thermodynamics is also needed
Learn now. You have everything i guess.
sir please send me fm1 complete lecture set
Voice is not coming
Kash IIT clear kar jata
sound isn't coming...:(
only on the right, there is no stereo sound
take out the plug a little
thank you...
Can I get a copy in English?
shove it, you are an ingrate😱
+Isaac Ayodeji go pound sand, fuckbasket
Shove It you are a fucking FART! by the way you write. Dumbwit!!
Thank you so much. Sir...
ty very much sir
