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
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.
Well , very well, to much well explain
Thank You 😊
Best faculty I ever found on TH-cam
Thank you so much

Thank You so much Nizam for your words.. 😊🙏
great lecture,, at last i understand npsh
@@NrMd-k4g thank you
super bro , i got idea from your view
@sankarkrishnan1148 thank you
amazingly explained.. keep it up
Thank You 🙂
Good explanation
@@NadeemSahu7232 thank you 😊
Bahoot hi achha 🙏❤️
Thnkss
thank you sir for explanation
Thank You 😊
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

You are welcome
Thank you Sir

Nice vedio
Thank you
pure term ko idhar laydnge to hs negative nhi hoga kya
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
dono ka difference toh negative hua na sir
We have three pump different npsh
2.23,2.91,3.69
Which one I chose
What is rojo? Pg u have mentioned in formula?
Pg is pressure X gravitational which is also equal to "w" means specific weight
Sir barc ka aaj hua exam ka cut off video bnaiye please stipendary cat 1 mech
Sure
@@mechanicalnexus sir aapke hisabse kinta questions sahi hona jaruri hain??? Unreserved category ke liy
@@passions...4112 uR ki post kitni hai?
@@mechanicalnexus 6
@@passions...4112 33-35 + approx... 1 seat par 5 or 10 they will call
I think that is suction head not a static head
why you don't use English for explaining siiiir..?
Here people want local language for easily understanding.
Galat explanation at the end
