- Hello Friends,
In this video we are going to understand what is NPSH, what is its requirement, and how to avoid cavitation in pump using NPSH.

Thank You
Well , very well, to much well explain
Thank You 😊
Best faculty I ever found on UA-cam
Thank you so much
Thanks Sir, jitni achi tarah se aap ne explain kiya, it's awesome ....aap ke video se pahle kayi videos dekha magar aap ki tarah explain nhi kiya hai kisi ne
Thank You so much Nizam for your words.. 😊🙏
amazingly explained.. keep it up
Thank You 🙂
Bahoot hi achha 🙏❤️
Thnkss
thank you sir for explanation
Thank You 😊
Hi Ashok, I hope you are safe and healthy!
I have a question for you. You described NPSH for a open system. How would you describe it in a close system (like boiler pump, condenser water pump). What variables change in that case?
Hi, Thank you, hope you are also safe & healthy 🙂.
In Open system only atmospheric pressure works which is only a static head, but in closed system atmospheric pressure as well as gauge pressure both will act here, It mean Absolute pressure equals to the gauge pressure plus atmospheric pressure.
Simple explanation
Thank you 😊
Sir p2/rho&g should be greater than pv/rho*g to avoid cavitation this is more correct definition for net positive suction head
Thank you Sir
You are welcome 😊
Nice vedio
Thank you
dono ka difference toh negative hua na sir
We have three pump different npsh
2.23,2.91,3.69
Which one I chose
pure term ko idhar laydnge to hs negative nhi hoga kya
What is rojo? Pg u have mentioned in formula?
Pg is pressure X gravitational which is also equal to "w" means specific weight
Is NPSH calc applicable for closed loop systems? I only saw open loop examples and nothing for closed system
Centrifugal pumps characteristics by npsh need. In closed loop system, pressure lost play important role.
@@mechanicalnexus can you give an example or refer me to guide explaining Npsh for closed loop system? Thanks
Sir barc ka aaj hua exam ka cut off video bnaiye please stipendary cat 1 mech
Sure

why you don't use English for explaining siiiir..?
Here people want local language for easily understanding.
