Thank you for this video .. excellent explanation and animation. My questions to you are regarding pressure heads achievable in a multi-stage centrifugal pump and are as follows:->> Since the input to output flow rate of the liquid is unaffected and kinetic energy of the fluid is dynamically exchanged for pressure head build up .. Q1:->> Assuming unlimited motive torque is available what limits can be applied to the pressure head achieved in terms of pump stages and does there come a PRACTICAL point, (for a given liquid, say water), where adding more pump stages makes very little difference to final output pressure head? (Diminishing Returns). Q2:->> What sort of pressure heads are achievable ... >10 BAR? >100 BAR? > 1000 BAR? It is understood that other constraints will effect the maximum pressure head achievable, (seals etc.), but my question, (Q2), is asked on the basis of the "centrifugal pump working principal" alone. That is to say the theoretical limit. An answer from you would be appreciated and once again, thank you for the upload.

The multistage pump u have shown is actually an multi impeller pump or a centrifugal compressor and in a multistage pump there should be a heat exchanger inbetween every stage
What about axial flow pumps sir ,is there any link available in your web site,please share to me .I want go with both centrifugal and axial flow pumps.
@@HardHatEngineer Low vapour pressure is actually advantageous. High vapour pressure is not desired. Cavitaion happens when pressure drops below vapour pressure. Therefore when vapour pressure is very low, too much drop in fluid pressure is req to cause cavitation.

Good
Thanks! Keep sharing.
Great topic
Thanks, more videos will be released from next week
Full article on pumps and it's types

Please make video on different types of Equipment used in oil and gas sector with its function
Will do it in the future

Hi sir please make video on pump head calculation for HVAC, THANK YOU . I Am from Dhaka, Bangladesh
Sir could you please tell me how to read pipe spacing chart ,I m having problem with

Hi, I think you should check again with some good reference. It is not the way you are saying.
Sir which pump is used for edible oil flow at different speed for pouch packing machine
It is flexible flow centrifugal pump.
What about axial flow pumps sir ,is there any link available in your web site,please share to me .I want go with both centrifugal and axial flow pumps.
Reciprocating Pumps are not yet covered. Will do after this series.

सर जी
आप की वीडियो जानकारी से भरी हुई थी लेकिन यदि आप हिंदी में वीडियो बनाओगे तो कुछ ज्यादा समझ में आएगा हम हिंदुस्तानी लोगों के

Don't give false information.
Hi, I am open to correct. But first let me know what is wrong?
Also, Let me know your source of correct information so that I can update myself. Thanks in advance.
