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?

[@mechanicalnexus]

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.

Thanks sir

You are welcome

Nice vedio

[@vikramsinghshekhawat3448]

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

pure term ko idhar laydnge to hs negative nhi hoga kya

[@tarunprajapat795]

We have three pump different npsh
2.23,2.91,3.69
Which one I chose

[@rkanjan]

dono ka difference toh negative hua na sir

[@slengoslengaw8510]

Is NPSH calc applicable for closed loop systems? I only saw open loop examples and nothing for closed system

[@mechanicalnexus]

Centrifugal pumps characteristics by npsh need. In closed loop system, pressure lost play important role.

[@slengoslengaw8510]

@@mechanicalnexus can you give an example or refer me to guide explaining Npsh for closed loop system? Thanks

[@RajeshKumar-oh9np]

What is rojo? Pg u have mentioned in formula?

[@mechanicalnexus]

Pg is pressure X gravitational which is also equal to "w" means specific weight
