sir your videos are great ,our concepts are getting clear with these videos !! , can you please upload the video of model analysis? it ll be very useful for us !!
hey @rohit chowdhury ur video is just awsome can u plzz upload the 2nd part n if possible can u explain the velocity diagram of cetrifugal pump it would be a great help ..... my exam is on upcoming 7th your videos are helping me a lot if possible upload the following topics it would be deeply appreciated thnx m8
@@RohitChowdhury_sajaysaini Sir, I am having a hard time calculating the exact discharge using a pipe of 50 mm dia. Please sir let me know the approx HP i will require. Thanks
Pumps don't suck water. They lower the pressure in a pipe. The result is that the weight of the atmosphere can then push the water in the reservoir down and into the low pressure pipe. It is an important destinction. It is the reason there is a limit to how high you can place a pump in relation to the reservoir. It depends on how much atmosphere you have pushing down.
Its a nice video on centrifugal pump. However, my concept is not yet clear on what is the difference between the pump head and system head. Both the pump and system curves have the similar x and y - axes values (i.e. Head vs flow rate), but we get different shapes. Thus, I would highly appreciate if anyone could assist me with understanding this. We tried to plot the pump and system curves with simple experiments, but got stuck in how the system head differs from pump head. I know the pump head is the head generated by the pump while the system head is the head required by the system. We can calculate the system head using equations, but not sure how to calculate pump head. Many thanks in advance!
Dear Sir , thanks for the video.....our lecturer has given us a task on this topic....and this is what he ask...try to google search but not able to find it...the question goes..... What is the “fundamental equation of centrifugal pumps”? What does each term in the equation mean to the working of a centrifugal pump?
The reservoir at lower height is experiencing higher atmospheric pressure than the reservoir at higher altitude...as we know pressure decreases with height..can you plz clear this concept of mine...otherwise the nuce explanation
Sir meri engineering complete Ho gayi per mera turbo machine jo 3rd year Ka paper ha abi tak back hai yee mera 6th attempt hai help me sir Mai Pune university 2012 pattern ka hite help needed plzzzzz
rancho baba see its very simple. Consider my higher reservoir as a water tank..now water tank is kept at a higher elevation because when water comes out from there through pipes ,it comes out at a high pressure because of the heigt.....now to refill the water in the tank ,you need to transfer water there with the help of pump....thats it
patel dhaval here nowhere I have talked about impeller rotation...if you r talking about that small diagram in the beginning,,then yes rotation is on the reverse direction.....that was just a simple example to eplain priming of pump I think....
+Jaydeep Guha my dear friend of a object is in a higher level offcourse it is going to have more static pressure. We know p= row *g*H......to have higher pressure water tank is set at such a great height

Himanshu Khandelwal you search for centrifugal pump lecture 2
Great job
Awsm video
upload frequent vdo and also problem solving
Thankyou for your video sir.
Dear Rohit Chowdhury you mentioned a book written by a professor can you attach a link to it
+ELF Linux professor Som biswas.
Thank you sir 👌
What about horizontal travel?
Sirji pls upload the lecture on centrifugal compressor and axial compressor of turbo machine.
Sir, please inform me how to draw the center line of a pump?
Sir, how much HP is required for lifting water up to a height of 280 metres ? Please help
You have to know the discharge first. Then P=row.Q.g.H

How higher elevation means higher pressure????
Can u tell me what is saturation pressure?
+kumar pritam saturation presaure is that pressure in which the air can hold the max amount of moisture
Anybody can explain what h in is?

Good lecture, which book r u following?
Luiz Sica som biswas
no vdo on kaplan turbine why
Shubham Kumar no specific reason..it is comparatively easy to understand than these
bhai priming bta do centrigugal pump ki
tomorrw morning it will upload??
Sarthak Jena yes it takes a lot of time because its of 1.65 gb
ok
thank u 4 ur respond sir
I have studied as we go up from sea level pressure decreases. ...nd u r telling higher elevation means higher pressure how?
rancho baba my dear friend you r talking about atmospheric pressure
rancho baba have you noticed that all the water tanks are made at such a higher elevation..why???? So that you get hivh pressure
Let me ask u something to increase npsh pump should be kept low or high
Rohit Chowdhury .....m telling about hydrostatic law not only for atmospheric pressure
rancho baba see its very simple. Consider my higher reservoir as a water tank..now water tank is kept at a higher elevation because when water comes out from there through pipes ,it comes out at a high pressure because of the heigt.....now to refill the water in the tank ,you need to transfer water there with the help of pump....thats it
plz upload the 2nd part rohit chowdhury ji
Sarthak Jena tomorrow u all will get it..surely
Good video..book name?
+sri balaji som biswas is very good book.if you read line by line any chapter..your concepts will get better
thank u sir
fine !
And cavitation too
Clear
The explanation of how the fluid is transferred from point A to C is not clear.
Richard Parker!!
plZ upload sir......
Sarthak Jena I m sorry fr being late..its aldready uploading...by tomorrow morning it will be over
Rohit Chowdhury tomorrow it will upload???
Pump direction of rotation is wrong , please correct it
But you did not add bend losses
Abu Taher I hv jst neglected it in this case..becz it is not that imp.
but impeller rotation is wrong ,
rotation is opposite side
patel dhaval here nowhere I have talked about impeller rotation...if you r talking about that small diagram in the beginning,,then yes rotation is on the reverse direction.....that was just a simple example to eplain priming of pump I think....
Rohit Chowdhury ok
Thizz iz tooo long ...make it short way ...then it will much better
That was not in a higher pressure that is in a higher lavel.
+Jaydeep Guha my dear friend of a object is in a higher level offcourse it is going to have more static pressure. We know p= row *g*H......to have higher pressure water tank is set at such a great height
