After watching countless videos on centrifugal pumps, I can comfortably say that this is the most well explained on the subject. I am Process Technician trainee and I find this very helpful. Thanks man.

Wow, thanks!

[@kirtan061]

@@savree-3d how suction is happening on the first place pls can u explain

[@MuhammadRahatLatifTousif]

​@@kirtan061 I think suction is carried out because of Negative force. The impeller rotates, forcing the air to flow out from the casing. This creates a vacuum in the volute casing which draws the water to flow inside.

[@southpaw8168]

Negative pressure or suction pressure is created at impeller eye by high velocity of impeller as we know when velocity increases pressure drops and vice versa after suction of water it is imparted high velocity by impeller and by increasing are of volute casing kinetic energy of water is converted to pressure energy hence water is delivered. Thank you so much for such wonderful clear presentation of working of centrifugal pumps. I wish you made such video for reciprocating pump too. Love from India. 🇮🇳🇮🇳🇮🇳🔥🔥🔥

[@Megabyte_gh]

Too good to be true ❤

[@rongarza9488]

Great presentation! BTW, if the impeller blades were bent backwards and their spin in the volute casing remained the same, the fluid would still be pushed out, with an even higher pressure. The fluid would not get sucked in from the volute casing. I missed this question on an IQ test. Now I think of it as "everything spins away from the center, regardless of blade curvature".

[@PertupDelom]

Sir, if the centrifugal force, acting on liquid particles, is the only motive force for pumping, there would not exist a centripetal pump there. There is centrifugal, static and dynamic head, which add to the total head created by a pump. At 9:34 - the comment about increasing pressure in azimuthal direction of volute is misleading. Volute is collector, which ideally works with constant pressure distribution (at a particular flow rate) around whole impeller outlet. The increasing area of volute in azimuthal direction is due to increasing inflow (outflow from impeller) in the azimuthal direction. There is azimuthal velocity component decrease, due to constant azimuthal momentum in volute if its radius is increasing. The diffusing part of volute casing is usually placed downstream the throat of the volute. The effective flow cross section is perpendicular to streamlines. It is not correct to compare cross sections by comparing corresponding projection lines between two neighboring leading and training edges of impeller interblade channel, as it is not perpendicular to the stream lines. The activity for public awareness of a pump working principle is appreciable, though. Thank you.

[@mayankdixit3747]

@saVRee 3D What is the need of converting kinetic energy to pressure Energy? Why can't we discharge it with kinetic energy only?

[@barsgursoy5976]

There is no thing such as pressure energy. There is potential (Static Pressure) and kinetic energy (Dynamic Pressure) . The one he is talking about is converting potential energy to kinetic energy.

[@YassineBoubcheur]

Good explanation ! But what happens if we dont increase pressure but instead we let water flow with high velocity ? Thanks !

[@gloomyend1232]

Umm just a doubt If in a straight pipe on increasing area velocity decrease and pressure increases along length then after a certain length the pressure at the end of pipe will be higher ,so won't liquid start flowing backwards?

[@mje3055]

[@daved3494]

Excellent explanation. Doesn't the volute increase in csa because more fluid is entering it from the impeller vanes? A lecturer I had once called a pump simply, a wheel on a stick.

[@rodneyspence7441]

It's kind of counter-intuitive, seems like water moving at higher velocity would exert greater pressure - not less. Thanks.

[@ian10quan]

Great video! However, I have a doubt, is there any explanation for the orientation of the impeller blades? I would have thought of an opposite orientation so the blades push the water in the same direction of rotation. Or does it work not by pushing the water but by suction? And then, comparing it with a francis turbine, does both of them have the same orientation or it changes and why? Thank you!

[@disrael2101]

doesn't pressure increase should correlate with the speed? as the smaller the hole the speed increase that makes sense but i thought the pressure should increase as well due to the narrower hole and the quicker flow or?

[@barsgursoy5976]

Great point. When he says "pressure" he means static pressure. The one you are talking about is "dynamic pressure". Think about it this way, if you have a baloon filled with some air and enclosed, it has some pressure in it. When you squeeze it, you feel that it resists your squeeze. Total air in the baloon is the same, so compressed that air and increased its static pressure. Now if you open the cap of the baloon, the air will leave it faster than if you have not squeezed it. In short, you first increase the static pressure and then convert it to dynamic pressure ( in other words flow speed). Now, in case of water, since it is not compressible ( in practical terms) when you squeeze by forcing it to accumulate through the outer diameter of the impeller, you directly convert static pressure to dynamic pressure ( velocity)

Which software you are using which is allowing you to move your cursor inside the model?

[@Saikiran-qb2yo]

I think the impeller must rotate anticlockwise direction..

[@crisantojr.robles4357]

Got confuse Sir,,,,because Pressure is inversely proportional to Area. P=F/A you said as the Area increases the pressure also increases...I think this is wrong....

[@paqanini]

If you are going to look from F/A perspective, then F is also different in that case, because in the section with bigger Area you should also consider the change in the Force = Mass * Acceleration and we know that the Mass will be higher in the zone of bigger Area. Bernoulli's principle is more based on the mass conservation principle, so when you have the static flow rate in the pipe the Mass * Speed for different cross-sections should be constant. It means, that in bigger areas the velocity will be low and vice versa. Knowing that the energy is also conserved the Bernoulli's equation should be satisfied

[@mr.nobody8784]

U r great sur

[@rishigautam9295]

How does impeller eye creates negative pressure?

[@barsgursoy5976]

It does not. Water itself creates negative pressure. Water cannot be compressed or expanded ( in scope of this pump example and in its liquid form ). Think of it this way, water is long fibers of string and when you pull from one side, all string will follow. Water does the same thing in propeller. You force it to move outwards ( you are pulling it outwards) and every water molecule pulls its neighbouring molecules outwards. Water molecules are held by hydrogen bond. So, if you pull more than the hydrogen bond can handle, you simply rip apart some molecules from its neighboors and create cavitation ( Steam or gas phase)
