Working of a Centrifugal pump is explained in this video lecture. Here working of a semi open, single suction centrifugal pump is described in a detailed way. Construction details of volute casing and turbo machinery analysis of impeller, difference between backward curved, radial, forward curved blade impellers are described in this lecture. A detailed webpage of the centrifugal pump is linked here – https://www.learnengineering.org/how-does-a-centrifugal-pump-work.html

Centrifugal Pump Working
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?

nice vid
it's so amazing and very interesting, very clear
pls watch and comment your opinion, if you like pls subscribe

Thank you
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
what is the width of impeller b2??
tai lo
this is a radial pump, not centrifugal

Sir, can we use two centrifugal pumps to lift water at a height of 150ft.
One pump rest at base level and second one rest at a height of 150/2 ft.
It is for agricultural purpose
Its fucking sick to see so many complaints against such a great explanation.
Very interesting
Это то же са…мое
please make videos in Indonesian or videos equipped with Indonesian subtitles
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?
Do you know any book i could use to get all this info? Thanks mates!

Can I ask you why there is no involute case in vacuum cleaners? Thanks in advance
Wow, that audio was bad; way too robotic and choppy. Could not watch it.
are the inelet and outlet velocity in same plane?
I think there is a mistake where you mention increasing mass flow rate. The mass flow rate is conserved due to conservation of mass and that is why fluid slows down when are increases to compensate into this law. Please correct me if I am wrong.
สุดยอดมากครับ อิอิ

Do you know how blade geometry design?
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.

Sir please Hindi mai bataeye ha
