Centrifugal Pump Working

[@beeenjjjippp]

you have the voice of an angel.

[@muneeswaranganesan6711]

Thanks for uploading videos. Glad to hear more turbo machinery videos are on the way.

If a direction changing flow is associated with a high velocity, it always leads to energy losses. So it is clever to covert the dynamic part to static to minimize such losses.

witch 1 is ur 2nd video? could've/should've put it in the description or name the 2nd vid the same with 2/2! Spellcheckers are free; every browser has free add-ons for languages, spelling, text-2-speach that record MP3s. We engineers are the brains of factories, and can't allow any shortcomings!

[@small_ed]

Assuming steady-state operation, mass flow rate does NOT increase within the pump. The impeller imparts energy to the fluid which generates a high velocity; this velocity energy is converted to pressure energy within the pump casing. The pressure reaches a maximum at the pump outlet where the conduit in the casing has largest diameter and is aligned axially with the outlet piping. Mass and volumetric flow rate remain constant throughout this process.

[@SabinCivil]

'h' pressure head rise, 'g' is accelaration due to gravity, 'b' is width of impller blades.

[@Heatherder]

Width being the axial dimension along the center of the impeller?

[@SabinCivil]

Please watch the second video on Centrifugal pumps. You can get pump performance curves from the manufacturer. After deciding your system curve, you can select proper impeller.

[@santoshdere3640]

Ok

Hi we couldn't find what is a parabolic flow pump. Could you please suggest some reference for this ?

[@evgeniipalamarchuk2581]

Nice video, but you have an incorrect representation of forward curved blades. Outlet angle is ok, but inlet angle should still stay less than 90° (you just made a mirror image, that is not how it should be). Also, backward curved impellers are not mostly used because of power curve, but because they are the most effecient ones. Your motor will not burn out unless you are operating out of the designed range

[@albanefafah4773]

it's so amazing and very interesting, very clear

[@saketchandramishra2408]

great explanation

[@SabinCivil]

Usually reciprocating pumps are used for pumping concrete.

[@Engineer2009ahmed]

dear "learn engineering'' I would like to ask you kindly to provide me with a written material for assembly and disassemble centrifugal pump. In addition, common problems for this kind of pump.

[@ajayjoshi9256]

in one of the other lectures they explained that the volute casing is of increasing area of cross-section because it reduces flow velocity as we move along the direction of flow which in turn increases pressure energy and thus helps in overcoming resistance now they are saying flow velocity remains almost constant ? can you explain which one is true?

[@danalex2991]

sir , How does the volute casing act as a diffuser ? ( and hence change kinetic head to static head ) . A diffuser should have only one inlet and outlet right ? ( Please correct me if im wrong ) But in this case the volute casing has multiple inlet points ( infinite maybe ) at all angular positions and only one outlet . Hence isnt the sole purpose of the volute casing to accomodate increase in mass flow rate ( coming in from different angles ) and hence to maintain constant flow velocity at all angular positions ?

[@Poteba_]

Can I ask you why there is no involute case in vacuum cleaners? Thanks in advance

[@ak33m98]

This may seem like a silly question but at 3:45 what do the variables 'h', 'g' and 'b' represent. I'm guessing 'h' is the change in pressure? but what about the other two?

[@jserra1176]

Do you know any book i could use to get all this info? Thanks mates!

[@tapu855]

good explanation

[@relaxnature9879]

Sir, can we use two centrifugal pumps to lift water at a height of 150ft.

[@Cplusplus745]

Its fucking sick to see so many complaints against such a great explanation.

[@yonatanshenhav1208]

Why is the mass flow bigger as the flow comes near the outlet? The same flow flows from starting point A to outlet B, how can the mass flow get bigger?

[@sodaman2006]

This looks a lot like a Nautilus sea shell with a few mods. Nature as teacher.

[@IUnknownxI]

great video.

[@Distilledroutes]

fantastic one.. thanx for sharing

[@MacStrange]

Very interesting

[@jimibhatt4945]

Good video...thanks

[@aniketsingh19193]

Awesome explanation..thanks a lot :-)

[@preechasuanmali6327]

สุดยอดมากครับ อิอิ

[@SabinCivil]

Check 2nd video on centrifugal pumps to know more about this.

[@amit2196]

sir plze upload video on different type of bearing and its application

[@shyams9658]

Great👍

[@GauravGupta-pb8mk]

Thank you

[@gospelhubdigital]

Why the Radial Blades should be unbalanced? I do not understand at all.

[@verminer7]

i like your videos buy when you start with pump SUCK fluid from the eye on of the impeller, its just wrong and it misleads people whos looking for knowledge

[@chiragmishra570]

are the inelet and outlet velocity in same plane?

[@abdulla93khalid]

Excellent work but for my opinion if a real person talks it will be batter then a computer.

[@swayingGrass]

Nice vid. But is it good for pump oil at high RPM?

[@seymourfroggs]

If you want pressure, the answer from the video is "no".

[@isaacaddy1047]

Please sir, what will a continues increase in the rpm result in. Pls respond. Urgent. I'm a farmer.

[@mohamedabdelmageedmohamed534]

pressure will raise until pump material failure (impeller)

[@mohammedahmed-ek5em]

waa cashar muhiim ah

[@kaushalpatil6326]

nice video

[@pratikkadam4862]

Nice video

[@AboutComposites]

Perfect! Thanks guys :)

[@Sirriebo]

I would like this video if the Robotic voice was actually understandable, it's a simple subject made difficult by the voice.

[@orhirshfeld]

great stuff

[@rakshithgowdab3205]

superb

[@HussainAli-fk4zr]

hello im wondering what is the effect of inlet head on the performance of the pump ? and what is the effect of change in kinetic energy of the fluid if the inlet and outlet pipe diameters changes from 25mm to 32mm? I need ur asistance asap please

[@hafizuddinmohdlowhim8426]

Do you know how blade geometry design?

[@nazmulhaque5612]

Thanks a lot

[@zainalabidinusemahu]

how to lower the booster pump pressure on the reverse osmosis system ?

[@relaxnature9879]

One pump rest at base level and second one rest at a height of 150/2 ft.

[@tiffanyedwards5722]

do you people have a problem with the word 'the'

[@rathoreJaipurr]

Hello sir , are you still there 🧐

[@kameshmahajan9358]

what is the width of impeller b2??

[@chaluvadi]

Why should we convert dynamic to static energy by using casing ? At all why are we interested in converting dynamic to static energy ?

[@zawmin8738]

Thank you somuch😁

[@widiabdulkodirdanu5816]

please make videos in Indonesian or videos equipped with Indonesian subtitles

[@albertaromin4324]

can this pump be used for pumping cement plaster? thanks for the reply

[@chalapathiraokottapalli574]

No

[@BOJEGOWDAMH]

good one

[@fdeam]

what is the b2 that appear in the equations?

[@stukegl2924]

how do you get from the h,Q to the P,Q diagramm? P=h*g*rho*Q ?

[@lokeshnarayanan1996]

super video

[@dooshtoomun]

Can anyone explain why tangential velocity at inlet = 0? How come he changed the angle of the fluid velocity at the inlet from some angle >90 to a right angle (3:16)?

[@SabinCivil]

dooshtoomun At the inlet, flow is entered radially. This makes the tangential velocity zero.

[@dooshtoomun]

I see. Thanks LE.

[@rubencontreras3553]

1:26 to 1:30 -- "...along the length of casing mass flow rate increases..." Can anyone tell me why does the mass flow rate increase along the length of the casing?

[@hiteshgchakrapani3610]

Ruben Contreras I think as there is increase in area which is leading to accumulate more mass

[@ramonhamm3885]

Good explanation but the computer voice is awful.

[@alb9mh]

what do you mean by b2 in last equation?

[@_PraveenSingh_]

i think it's the width of impeller blade.

[@relaxnature9879]

It is for agricultural purpose

[@muhamadsukron9180]

good

[@bobbysingh-ff1xj]

[@vishalchoure1993]

Hahaha nice comment

[@HelloKittyFanMan.]

Geeze, what's with the robotic voice?

[@santhanaponnoiy2772]

THANK.

[@kryten93]

For a minute there I thought I was watching some odd Anonymous video or something.

[@adibasdas]

this is a radial pump, not centrifugal

[@jameslaine2472]

Wow, that audio was bad; way too robotic and choppy. Could not watch it.
