that's the type of teacher we engineering students look for...but rarely get...thankyou so much...

[@abhaykumartiwari1216]

True

i guess im asking the wrong place but does anybody know of a trick to log back into an instagram account? I was dumb lost the login password. I appreciate any help you can give me.

@Kyson Bruce instablaster ;)

[@kysonbruce1767]

@Lyric Troy Thanks for your reply. I found the site thru google and Im trying it out now. Takes a while so I will reply here later when my account password hopefully is recovered.

[@kysonbruce1767]

@Lyric Troy It did the trick and I actually got access to my account again. I'm so happy! Thanks so much you really help me out !

[@sigmainclination9483]

this is called teaching ...awesome sir the way u blends practical happenings with theory really great proud to hear u

[@SuperJJMCG]

my right ear loves this

[@vaibhavbansal625]

+SuperJJMCG go to stereo in your vlc and swith it from neutral to right.

Hahaha

[@nathankaiser2044]

One of the greatest lectures Prof, very high quality teaching, god bless you

[@sumitmalviya9910]

Thanks a lot sir!! You are an " incredible teacher ". Thanks to NPTEL!

[@SrinivasPanchmukhi]

Thank You Sir. We need motre teachers like you in every institution. We all miss you sir.

[@Subham_Lohan]

I am very very Happy after watching this lecture!!

[@mukeshnayal234]

@ prof.s.k.som . sir there is little mistake over there .you made Qb=t2(s2-s1) and Qc=T1(s1-s4') but this should be Qb=T1(S1-S4') and Qc=T2(s2-s1) thank you !!

Thanks sir... I am getting so much help from your lectuers...🙏

I THANKING you sir for this wonderful lecture. THANKS A LOT.

[@Shivai1215]

NPTEL is blessing in disguise.

[@bsastarfire250]

As a practicing Engineer I thought this was good and liked the music!

[@29akhil24]

Can we change heat completely in to work in a non cyclic process?

[@vaishnavisharma1853]

Simply genius teacher!!

[@dhirenpanchal5766]

nicely explained all the topics...

[@justinhare905]

Thanks Prof....I have really understood

[@sheyinamos5917]

This is just superb

[@anilraghu8687]

Then we heat a working system which takes the heat from this burning gases and it executes the cyclic process and develops power. 7:08 Sometimes, this burnt products itself performs as a system of the cyclic process and produce power, This happens in IC engine. Sometimes, this burnt product produces the source of heat, where heat is given to another fluid or another system executing the cyclic process which happens in a steam power plant and produces power.

Best material to study from just one day before the termends :p..Great work sir !

So much very good sir.

[@bhukhapraani5366]

sir you are great

[@HarshPatel-gz4vv]

Thank u

[@ajaysaichandu2415]

why we use condenser here in cycle, however feed pump increases pressure of liquid.

[@bhavna9027]

To change the state(from steam to liquid) we used condenser and to increase the pressure we used pump

[@sahilrajeshgajbhiye4968]

ty very much sir

[@theAi_journey]

44:48 you wrote "h1-h4' =T1( s1-s4') " But dh=Tds +v dp ,1,4' are not at same pressure. So, you can't neglect v dp term. Can anyone explain this?

[@neerajkgond]

if the point 4' be inside dom then it will be correct.

[@atharva1913]

1,4 are at same pressure Since they both lie on constant pressure line

[@IgaSwiatekFan-ox9rn]

God

[@vini2844]

Sir written efficiency as Wn/QL ...is it Qn / QL or Wn/QL???

[@chetankapadnis5425]

It is Wn/Qb or 1-Qc/Qb

[@saisindhuja8829]

42:45 how can 1-2-3-4' be the same cycle when 1 & 4' are on different pressure lines?

[@rajat3744]

cuz in carnot cycle, heat addition is at const temp and not isobarically

[@satishdofficial9601]

I love u sir

[@akshpatel2868]

How can there pressure remain same where phase is changing? At condenser and boiler ?

[@riturajanand7133]

the pressure is dropped because of friction and sir considered all the system as steady in condition, frictionless.....think of the flow of fluid through a thin pipe

[@akshpatel2868]

@@riturajanand7133 but even by neglecting friction loss phase is changing here and how can we say that pressure of liquid and that of vapor is same since pressure exerted by liquid is more.

[@riturajanand7133]

Brother I guess you don't know phase change took place in condenser , right...and during the process whole system is vaccum out to maintain constant pressure...... without friction and in vaccum , pressure must be constant......I know you got the point

[@akshpatel2868]

@@riturajanand7133 oh yes I thought it is normal condenser. Yes if vacuum is there then obviously pressure remains constant. Thanka to point it out👍🏼

Sir agar feed pump nhi lagayenge toh

[@akshay1980]

agar ham log feed pump nai lagate hai to water ko boiler k height tk kaise pahuchayenge?

[@mayursingh7959]

Akshay Deshmukh Agar boiler ko turbine ke niche lagaya toh!!!

[@rahulakrgh]

nhi kar sakte because when water comes out from the condenser it has low pressure to increase the pressure we use feedpump

[@bhavna9027]

@@mayursingh7959 to steam ka temp aur badh jaega, aur condenser se liquid mein convert karne ke liye zyaada mehnat lagegi

Useless education

[@cyrolacorte6469]

I am from the USA and this movie looks like something made in the 1970's- India lacks in technology and modernity, the professor is probably 75 years old today. You Indians never cease to amaze me!

[@VIVEKKUMAR-lk8mn]

the video was uploaded 7 years back ...... & .if u want to see the modernity in us then watch the latest videos on steam and gas power plant system by IIT roorkee ........today we are leading the world ......for your concerned information sir..........the CEOs of top rank companies are indians not americans ............we constructed our own INS VIKRANT.....we reached on moon and you guys still think we lives in villages ....... we helped the bangladesh ...even when we were poor ....today we are rich .....think what we can able to do........i think you are living in 1970s....update your information about us ..... NAMASTE

[@prasantapal8107]

Cyro Lacorte .Hello USA boy. I think you are just concentrate on video quality only,not the content or lecture quality

[@PrashantKumarSomesh]

If your focus was on the content instead of quality, you would then have definitely appreciated it. Focusing on the content without any bias may help.

[@uniqorn2275]

even if you are from USA & consider yourself superior than us then why you are watching the videos of we indians ??? & yes, even if the sir is of 75 years old.....see his efforts to make his students educated so that the one who can`t reach upto them can also attend their lecture. I can understand that you will really get amazed when you see such old sir continue to teaching......because In USA such a old sir would have taken a retirement.

[@krishnakumarmahato7557]
