Today's lesson The draft tube is used in the turbines where the water from turbine which has negative pressure is to be discharged in the area of positive pressure. Draft tube is the tube which has varying crossectional area i.e increase area so as to reduce the velocity and increase the pressure from negative value to some positive considerable value...... Sir I am having one question over it Instead of providing draft tube can we provide there a cylindrical perforated pipe which will allow the positive pressure of surrounding atmosphere to convert the negative pressure inside turbine into positive pressure ?
Sir I have a doubt regarding how the pressure and velocity are inversely proportional when from continuity equation and pascal's law its showing directly proportional. Please clarify it sir.
The water molecules get more and more space as they move through draft tube because of which they collide with the walls of draft tube and even among themselves,hence pressure gets increased .
Nowhere have i found such clear and conceptual reason of why a draft tube is being used. Thank You Sir!
Thanks ,
Great explanation 👌 👌
Draft tube explanation is awesome sir 👍👍
For the first time, I understood the term negative suction. You taught the concept so clearly. Thankyou Sir.
What an legendary explanation 🙌
Excellent sir... Way of explanation is amazing
So easy to understand.. I completed my graduation and Now i learned this easy things.. THANKS SIR..
awsm explaination sir we need sir like you🔝
neeraj hebbhar we need a sir like you *
Great Sir, we want to listen more from you! Ye dil mange more!!!☺
great video... Hoping you could upload many more such videos explaining about hydro turbines!
Awesome teaching sir .....know my concept is clear
Fantastic video lecture!!
Awesome class sir....
Thank you Bro it is really helpfull
Appreciated work sir
so good :)

upload more videos about hydraulic..it's good to understand.👍
if possible upload about interlinking of river in india mega project.
ap great ho sir
Awesome!!
Beauty
Thx sir it was so good..
Wow i want you like teacher
Hello Sir...I have a doubt
Pressure=f/A
Then at inlet,where area is larger how pressure is more than outlet where area is less.
Please reply
Plse study venturi meter
which college is this .i want to join
K.K.W.I.E.E.R,NASHIK

Using Bernoulli equation you will be able to understand it
