Draft tube and its efficiency

[@kriteshdiwakar8241]

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

[@bittudangi6742]

One of the best explanation on draft tube...

[@sachinramesh1540]

Way of teaching is very appreciable.thanks🙏🙏

[@farahnazghanbari9957]

you are one of the best teachers that I have seen in my life

[@DeKubaMadre]

Better than my Uni Prof, great job !

[@ranjitpanigrahi5096]

Excellent video I have seen related to draft tube so far 🔥🔥🔥

[@satyajitroychoudhary1826]

Very knowledgeable information sir.

[@azadkrishna12]

awesome None have ever explained in such a way..👍

[@pankajkumar-do6rs]

Now i know the importance of draft tube... Thank you so much for this nice content.

[@ekvinaysayaraj6071]

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?

[@Dr.AmitMandal]

must avoid flow seperation while passing through....

[@anishsharma7331]

nice one sir....very easily u made it to understand...thanxx alot!!

[@pratik2583]

Excellent.loved it

[@sanipatel5974]

one of the best explanation..👌👍

[@MRDigitalEducation]

Thank you ..Came to know importance of draft tube from your video onlu

[@crackmech5931]

Thank u sooo much sir...u always make my doubt crystal clear...

[@mohammedrafath3370]

Wonderful lecture

[@akshaykumar-sb5iq]

very well explained sir

[@this_too_shaII_pass]

This is an extremely good video, thank you so much!

[@mvthought_]

Thank you so much sir now this time i've got satisfied answer

[@VikashKumar-vl4hv]

Thank you very much sir, the video cleared my concept about draft tube

[@akhiborntorock1]

As there is vacuum at point 1...the water can flow back from tail race to the point 1?? Possible right ?? If not why

[@JNL02023]

Akhil C Flow gets reversed if and only if , large work done against gravity ! It would require head (Gross head + H) & its not possible..😊

[@AnimeWorld-xe2mm]

as usual it is also the best explained

[@ashutoshsaini2978]

Really helpful thanks a lot

[@aman.easpur]

Diverging angle is generally taken 5 to 7 degree to avoid Flow separation.

[@subhanimohammed8384]

amazing explanation...extremely helpful..thnx a lot sir

[@ASHOKKUMAR-jn2xb]

Excellent explanation bro

[@shreyasbangera2140]

Thanks, that's a very clear explanation

[@dhruv3560]

best explanation

[@rajrajput9749]

Wow amazing....

[@vishalshakya4141]

Quality video.. Thank you

[@mrizalrizkihansyah8782]

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?

[@gauthamsathyaprabhua464]

sir...what is the use of decelerating the liquid coming out of impeller using draft tube?

[@aravind43]

Thanks for the video

[@Hopeforgoodd]

sir why shoud we use drft tube only for rectin turbine....

[@AG-id5fj]

Very nice explanation sir thank you

[@RIYAZHUSAIN]

wahoooooo... clearly explained.. thank you sir

[@AmpedUpWithKrishna]

nice explain

[@RajanKumar-xi8ds]

Very nicely explain.

[@Veenapappuri]

Sir excellent video

[@mrizalrizkihansyah8782]

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.

[@cosmos1701]

Nice Explanation

[@harshavardan8748]

Excellent video thanks

[@alokkumarnyati]

What a Dam good lecture

[@mathsanalysis8402]

Thanks a lot sir because I have understood draft tube

[@prem7556]

Thank you sir, cleared many doubts

[@ravindarsingh3002]

nice work

[@anveshsameer]

You said it is copyright protected, am I not permitted to take a picture of the draft tube from the video?

[@ishangupta1375]

Why negative pressure created ?

[@Khizar_Ansari]

What if we make it converging?

[@Dr.AmitMandal]

it will Reduce its efficiency

[@polashthoughts2052]

Its a helping one .Thanks.

[@pratikbose4399]

I request you to upload a video on degree of reaction....

[@VampSoul786]

how pressure becomes negative? (P2)

[@Dr.AmitMandal]

+vipuces its due to 'pull' of water content in downward direction...

[@thanithaweerasekera5240]

To the point, crystal clear. Thank you.

[@mohitbache8411]

-ve pressure hoga to suction crate hoga how is this possible

[@chirucvt]

Excellent super

[@abhishekbhandari3583]

Thx sir it really helpfull

[@alokdesai5326]

really helpful

[@farhanalix]

Thank you !

[@modassirahmed5712]

Why uou put p2=p0, we use hydrostatic only in static condition..

[@lalitsharma5114]

Sir aapka content to bahut acha hai But samajh nhi ata ki subscriber itne kam kyu hai

[@prithvirajgohil4163]

sir can you please make make video on "what will happen if we don't use draft tube"?

[@Dr.AmitMandal]

+Prithviraj Gohil low power developed.

[@prithvirajgohil4163]

Amit Mandal sir , so water will be discharged or not because it will be at low pressure as compared to atmospheric temperature.

[@Dr.AmitMandal]

+Prithviraj Gohil ya it will

[@thresholdfrequency9725]

Thanks a lot ...sir ..

[@rahulbhati4749]

sir governing of propelr turbine bta do plss

[@ShubhamMishra-ij8vg]

technically helpful for hydraulics....!

[@MANISHKUMAR-fv1em]

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.

[@Dr.AmitMandal]

P2 is less than Pa but greater than P1 . It appears you are confused with static pressure, dynamic pressure and total pressure.

[@Dr.AmitMandal]

Akhil , at point 1 pressure is higher compared to 2 , otherwise fluid can't flow toward draft tube...

[@akshaymanikjade]

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...

[@ravikiran3314]

its good... but make it short

[@civilzone5117]

good good

[@rahulbhati4749]

sir plss propeler turbine ki govrning bta do

[@shettipellikomal6421]

So does a draft tube increase the chance of cavitation ?

[@Dr.AmitMandal]

If not designed properly

[@saiganeshpinnam6317]

Thank you sir😃😄

[@lalankumar-qk2rf]

best

[@rahulbhati4749]

funtion bhi bta do sir drft tube ka

[@Dr.AmitMandal]

+rahul bhati to reduce head loss

[@mayankbhadauriya]

Awesome Explanation

[@prashantparaye3696]

plss upload on drafttube discharge angel

[@lokeshn.jeengar8015]

Thanku so much sir

[@maninderbisht9681]

thanks sir

[@keshavsharma4818]

Thanks..

[@sukanyasengupta8388]

excellent

[@miltondeon1031]

in efficiency why H is not added

[@shekarganthi2039]

nice
