Bhaisahab kya samjhate hain aap maja ajata hai dekh kar aur aapke us Knocking wale lecture ki wajah se mera Internal combustion engine and gas turbine subject clear ho gaya.Thanks i hope ki is baar fluid machine bhi ho jaye.thanks again sir
Thank you that you made me understanding the draft tube importance. This make me wanting to know more how to design/calculate the draft tube. Is it any limit to determine the H of draft tube, its longest length compared to whatever number such as diameter of A1 or A2 or compared to V1 or V2 or compared to P1 or P2...? or any recommend of of wide angle of the draft tube wall?
Sir, i hace a question. When the outlet draft tube on top surface of tail race and outle draft tube on surface of tail race. What is the difference between two case?
Sir, i have a question. When the outle of draft tube (sectioan 2) is above from water of tail race. How do we calculate the pressure on section 2? Please help me sir, thank you.
Thank u. Sir could u explain why pressure at point 2 is taken as atmospheric pressure?? If we apply Bernoulli's equation between water point 2 and outside water from draft tube it will give " Pa=P2+$V2^2/2 (take density by symbol $) " so sir P2 is less than Pa. Sir could u pls correct me.
One of the best explanation on draft tube...
Excellent video I have seen related to draft tube so far 🔥🔥🔥

Way of teaching is very appreciable.thanks🙏🙏
Better than my Uni Prof, great job !
you are one of the best teachers that I have seen in my life
Very knowledgeable information sir.
awesome None have ever explained in such a way..👍
Now i know the importance of draft tube... Thank you so much for this nice content.
one of the best explanation..👌👍
nice one sir....very easily u made it to understand...thanxx alot!!
Excellent.loved it
Wonderful lecture
very well explained sir

must avoid flow seperation while passing through....
Thank you very much sir, the video cleared my concept about draft tube
Thank u sooo much sir...u always make my doubt crystal clear...
Thank you ..Came to know importance of draft tube from your video onlu
amazing explanation...extremely helpful..thnx a lot sir
Wow amazing....
best explanation
Thank you so much sir now this time i've got satisfied answer
Excellent explanation bro
This is an extremely good video, thank you so much!
Really helpful thanks a lot
as usual it is also the best explained
Diverging angle is generally taken 5 to 7 degree to avoid Flow separation.
As there is vacuum at point 1...the water can flow back from tail race to the point 1?? Possible right ?? If not why
Akhil C Flow gets reversed if and only if , large work done against gravity ! It would require head (Gross head + H) & its not possible..😊
Nice Explanation
Sir excellent video
nice explain
Sir, i hace a question. When the outlet draft tube on top surface of tail race and outle draft tube on surface of tail race. What is the difference between two case?
Very nice explanation sir thank you
Very nicely explain.
Quality video..
Thank you
nice work
sir why shoud we use drft tube only for rectin turbine....
Thanks for the video
sir...what is the use of decelerating the liquid coming out of impeller using draft tube?
Thanks, that's a very clear explanation
wahoooooo... clearly explained.. thank you sir
Excellent video thanks
Why negative pressure created ?
Thank you sir, cleared many doubts
What a Dam good lecture
Thanks a lot sir because I have understood draft tube
You said it is copyright protected, am I not permitted to take a picture of the draft tube from the video?
how pressure becomes negative? (P2)
+vipuces its due to 'pull' of water content in downward direction...
Sir, i have a question. When the outle of draft tube (sectioan 2) is above from water of tail race. How do we calculate the pressure on section 2? Please help me sir, thank you.
-ve pressure hoga to suction crate hoga how is this possible
Excellent super
What if we make it converging?
it will Reduce its efficiency
To the point, crystal clear. Thank you.
Its a helping one .Thanks.
really helpful
I request you to upload a video on degree of reaction....
Thx sir it really helpfull
Thank you !
Why uou put p2=p0, we use hydrostatic only in static condition..
Akhil , at point 1 pressure is higher compared to 2 , otherwise fluid can't flow toward draft tube...
Amit Mandal Sir but area of draft tube is diverging so velocity is low and pressure is high then how come its possible.... pls demolish doubt...
Thanks a lot ...sir ..
sir governing of propelr turbine bta do plss
Awesome Explanation
Thank you sir😃😄
So does a draft tube increase the chance of cavitation ?
If not designed properly
best
plss upload on drafttube discharge angel
sir plss propeler turbine ki govrning bta do
sir can you please make make video on "what will happen if we don't use draft tube"?
+Prithviraj Gohil low power developed.
Amit Mandal sir , so water will be discharged or not because it will be at low pressure as compared to atmospheric temperature.
+Prithviraj Gohil ya it will
Thank u. Sir could u explain why pressure at point 2 is taken as atmospheric pressure?? If we apply Bernoulli's equation between water point 2 and outside water from draft tube it will give " Pa=P2+$V2^2/2 (take density by symbol $) " so sir P2 is less than Pa. Sir could u pls correct me.
P2 is less than Pa but greater than P1 . It appears you are confused with static pressure, dynamic pressure and total pressure.
technically helpful for hydraulics....!
in efficiency why H is not added
thanks sir
its good...
but make it short
good good
Thanks..
excellent
Thanku so much sir
Sir aapka content to bahut acha hai
But samajh nhi ata ki subscriber itne kam kyu hai
funtion bhi bta do sir drft tube ka
+rahul bhati to reduce head loss
nice
