[@ziky3329]

Sir, how much HP is required for lifting water up to a height of 280 metres ? Please help

[@RohitChowdhury_sajaysaini]

You have to know the discharge first. Then P=row.Q.g.H

[@ziky3329]

@@RohitChowdhury_sajaysaini Sir, pipe size is 50 mm.

[@ziky3329]

@@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

[@RohitChowdhury_sajaysaini]

if anyone watches this full video..and try to understand carefully..he will definitely get his concepts clear

Sir that vedio is too Good..... Upload 2nd part fast Plzzzzzzz exam # dec

[@pritamkumar4744]

Can u tell me what is saturation pressure?

[@RohitChowdhury_sajaysaini]

+kumar pritam saturation presaure is that pressure in which the air can hold the max amount of moisture

[@LeoRose]

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.

[@kuntaljana6717]

its awesome.. thank you sir.

[@himanshu4569]

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]

Himanshu Khandelwal secnd part and velocity diagram video is also there

[@RohitChowdhury_sajaysaini]

Himanshu Khandelwal you search for centrifugal pump lecture 2

[@elflinux3561]

Dear Rohit Chowdhury you mentioned a book written by a professor can you attach a link to it

[@himashirajapaksha2943]

wooww sir..superb 🙃

[@pravinkurade9734]

Sirji pls upload the lecture on centrifugal compressor and axial compressor of turbo machine.

[@sahroonkhan5555]

Sir, why the centrifugal pump sometime leaves water. What is the solution. please reply

[@a.k.s.1225]

there is also some bending losses also rohit

[@RohitChowdhury_sajaysaini]

Amit kumar yes you are correct..

[@jaypanchal1997]

Sir upload video on slip in centrifugal pump...

[@solomonreggae5952]

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?

[@RohitChowdhury_sajaysaini]

Thank you very much

[@sahidmd7492]

Great job

[@jayanthp7213]

Please change the direction of Impeller rotation.

[@RohitChowdhury_sajaysaini]

Jayanth P why???I didnt get you

[@tirumalkumar133]

He is telling about vanes.

[@md.abdullahalmamun1067]

Sir, please inform me how to draw the center line of a pump?

[@tfi2452]

Very nice explain. Help me sir to produce the same

[@RohitChowdhury_sajaysaini]

Times for indian definitely sir.

[@sarthakjena7718]

tomorrw morning it will upload??

[@RohitChowdhury_sajaysaini]

Sarthak Jena yes it takes a lot of time because its of 1.65 gb

[@sarthakjena7718]

ok thank u 4 ur respond sir

[@mahmudulhasan5219]

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!

[@AdityaSingh-hk8rc]

Reciprocating pump lecture is not available

[@hppylyf]

no vdo on kaplan turbine why

[@RohitChowdhury_sajaysaini]

Shubham Kumar no specific reason..it is comparatively easy to understand than these

[@someshshinde4992]

How higher elevation means higher pressure????

[@afri-can7739]

What about horizontal travel?

[@hppylyf]

i am having my exam on 22nd plz upload the 2nd lecture before that

[@rahulbhati4749]

bhai priming bta do centrigugal pump ki

[@LuiZoukeiro]

Good lecture, which book r u following?

[@RohitChowdhury_sajaysaini]

Luiz Sica som biswas

[@sribalaji3159]

Good video..book name?

[@RohitChowdhury_sajaysaini]

+sri balaji som biswas is very good book.if you read line by line any chapter..your concepts will get better

[@jasper78138]

I have studied as we go up from sea level pressure decreases. ...nd u r telling higher elevation means higher pressure how?

[@RohitChowdhury_sajaysaini]

rancho baba my dear friend you r talking about atmospheric pressure

[@RohitChowdhury_sajaysaini]

rancho baba have you noticed that all the water tanks are made at such a higher elevation..why???? So that you get hivh pressure

[@jasper78138]

Let me ask u something to increase npsh pump should be kept low or high

[@jasper78138]

Rohit Chowdhury .....m telling about hydrostatic law not only for atmospheric pressure

[@RohitChowdhury_sajaysaini]

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

[@nataliekatebemwaba5171]

Lovely, thank you!

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

Thank you sir 👌

[@CraftCreatorKC]

Thankyou rohit

[@andikahutabarat5639]

Anybody can explain what h in is?

[@MR-RAY..]

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

The explanation of how the fluid is transferred from point A to C is not clear.

thank u sir

[@iambrownfrom83]

Pump direction of rotation is wrong , please correct it

[@pateldhaval8596]

but impeller rotation is wrong , rotation is opposite side

[@RohitChowdhury_sajaysaini]

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....

[@pateldhaval8596]

Rohit Chowdhury ok

[@jyoshnajyoshna6021]

Thizz iz tooo long ...make it short way ...then it will much better

[@MirajulIslam-el4ge]

fine !

[@ikennaokonkwo2898]

Richard Parker!!

[@sahidmd7492]

Clear

[@jaydeepguha5693]

That was not in a higher pressure that is in a higher lavel.

[@RohitChowdhury_sajaysaini]

+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
