I have try to understand the concept of npsh sice last 2 yr. As this question was asked to me in asian paint company and i was given therotical definition and he was not satisfied.
Today first time my concept becomes clear. Thanx..
Most welcome 😃
I hv watched lots of vdos since before regarding npsh and how liquid boils at low pressure at any temp but I did not understand completely in any vdos but today my all doubt have cleared thanks a lot🙏🙏🙏
Most welcome
such a great effort Bhai...I always tried to understand NPSH but couldn't satisfied...now after lots of efforts, you made me understand... hats off to you brother
Thank you so much ♥️
Your way of explanation is superb by introducing images ... thankyou 👍
Most welcome ♥️
@4:51, Chalo friends ab samajhte hein NPSH ka funda..thats cool
Lot of clearty
Superb Sir, your teaching style is very nice....fundas gets cleared
Excellent effort. Totally satisfied with your explanation. Thanks
Thank you so much❤
Very good information and very good explanation Sir 👍👍👍
Thank you so much dear ♥️
Awesome explanation in simple words.
Your explanations made me to subscribe your channel.
Thanks
Thank you so much❤
Nice video.
Your explanation is very satisfactory.
thankyou sir.
Most welcome dear ♥️
Your video tutorial very helpful with great explanation I request to you please start series about energy auditor syllabus with full numerical calculations
Sure
Great Sir...Thank you
Sir you explained very well, just please try to shoot the video in good quality so that it will be more easier & interesting for subscribers.
Good explanation sir ..
Ab aap Berometric head kaise nikalte hai ..aur pump ka seal pane p details se vedio banaiya
Please make one video on barometric head.
Sure dear I'll make
Sir with due respect apke video se bahot sikha hai pr yaha ek correction Krna hai bubble explode nahi implode hoga due to excess pressure explode nahi ho paega implode hone se cavitation hoga jet formation ki vajah se explode me jet formation nahi hoga
Maza aa gya sir video m
Thanks a lot dear
Very good video
Great sir ....🙏🙏🙏🙏🙏🙏🙏
Thanks dear
Nicely Explained...Thank you!
Most welcome ♥️
Great sir
Sir ji nice explanation....
Thanks dear ♥️
Sir Eccentricity kaa Concept mein abhi bhi Confusion hai thoda clear Karwa dijiye 🙏
Please start series of cooling water chemical treatment...
Sure very soon I'll start
Nice video keep it up
Thank you so much ♥️
Nicely explained
Thanks a lot
Amazing explation
Thanks a lot
Please make video on lube oil system of diaphragm compressor
Reciprocating air compressor ka detail me video banao .. or suction discharge Valve working and assembly
Power plant Boiler DCS में video बनाईये sir ,all parameters and input and correction method? DCS operation method ?
Sure dear I'll make
CEP PUMP K WORKING DETAILS PER EK VIDEO BANAYE SIR . BALANCING LINE DETAILS K SATH .
Sure dear I'll make
Sir please make a video upon compressor, compressor screw cooling using oil and cooling through water.Mainly discuss about oil tank in compressor (use of DP TRANSDUCER, THERMOSTAT & it's recirculatione)
Very soon dear I'll make video on this topic
👌🙏wish you happy dipavali to you and your family 🎇🎆🎊🎉💖🙏
Thank you so much
Please create video on pump for semi solid material like fly ash mixture of 1700 density
Thanks 👍
Most welcome
Awesome sir
Thanks dear
great
Thanks
Awesome
Thanks a lot
Sir i request you 🙏 sir khali pump chlane se kya nuksan ho skta ya section na milne se kya ho sakt h plz sir video jarur bnana
Sir I am asking privous comment ple explain PA nozzgle velosity and feed water and steam velosity calculation with example.
Dear I have already completed this video very soon I'll upload, please wait for the video.
@@PowerPlantDiscussion I am also waiting of that lecture.
Nice explain sir 👏👏👏👏
Thanks a lot dear
Very good
Sir, clarify my doubt.. what's the purpose of using prds???? Explain fully about prds sir... Pls
Used in ejector system for creating vacuum
Sir pls upload video for turbine governing system with Instrumentation and control loops explanation
Sure dear I'll make
❤️❤️❤️👍
Super explain sir...
Thanks a lot dear
Good...
Thanks
Dear sir conductivity
Or BFP ki efficiency pr video banouu sir
Dear BFP efficiency wala bahut jald hi upload kr dunga av m pump series m hi work kr rha Hu, please wait for the video.
Thanks
Too good sir
Thanks a lot dear ♥️
Nice video 👍
Thanks❤
One more thing .. What is the GD² value (Inertia) in centrifugal pump , and is there possible that GD² value of pump is Greater than the GD² value of motor (Prime mover), If not than what will be the effect? Kindly explain
Sir jiii v good explainationn🤗
Thanks a lot dear
Steam turbine k bary be bta dain. Thx sir
Already uploaded many video
Good
What is difference PLC & DCS system in operation????
Vacuum balancing line should be closed after running the pump ??
I read on a name plate of pump, it ia written than npsh = 0.25 meter.
What is the meaning of it.
I understand that in any pump suction pr at the eye of imperller shall be greater than its vapour pr. and lower than atm.pr.
How 0.25 m ask us that it is lower than atm pr. But greater than vapour pr.
What is the meaning of npsh =0.25
NPSHr value is given and it can convert into pressure by
P = 0.1 × H × Sp. Gravity of water
My next video on Calculation of NPSHa & NPSHr
@@PowerPlantDiscussion
Thanks for the reply.
What is H,
Option 1. Is it only Discharge head. ( means pr. at the pump dicharge)
Option 2. Total head ( Discharge head - suction head) .
Waiting for your next video.
👌👌
Thanks a lot ♥️
Sir please teach us the NPTI books
Plzz
Muze combipak 6ton fire&watertube boiler ke baare me jaankari chahiye (thermax)
Sure m trying to explain
OK friends thanq
Hello Sir, jab positive suction ho open container me., then NPSH ki koi need nahi rehti h kya ..?
Bhai aayega natural draft heater pr video kyuki bhai bahot baar bol chuka hu
Ye topic really mere mind m h aur pump series bd m heater topic hi choose Kia hu, please thoda sa time dijie definitely I'll make on this topic.
Thanks
Please upload a vedio about boiler gauge glass
Nice
@@PowerPlantDiscussion ok bhai
Sure I'll make
Wheel chamber me kitna pressure drop hota hai uska ak formula bataiye sir..
Kitna % pr. Drop ho raha hai o nehi matlab furmula hai kuch oo boliye sir plyz...
Ar sir 100ton ka boiler hai to uska BFP ka flow kitna hona chahiye
Reply plyz sir...
If u dont mind in which company u work..
Please contact me through my email powerplantdiscussion@gmail.com
I can't share my personal information here.
Sir lekin suction pr. Kaise pata karengre ek pump ka
How to calculate shut-off pressure in centrifugal pump?
In Which type of Suction NPSH is important?
By closing discharge valve start the pump and gradually increase speed upto full, and watch the discharge pressure, that pressure is call shut off pressure
@@PowerPlantDiscussion How to calculate shut-off pressure by mathematically?
Means If pump capacity is 20 M3/hr. what is maximum shut-off pressure?
I still never study about mathematical calculation.
In which type of Suction NPSH is more important?
Positive Suction or Negative Suction?
Both conditions NPSH is necessary other wise Cavitation occur.
Steam jet ejector plant me uper kyu rakha jata he
What will happen if NPSH=0 ?
Sir easy language mein answer dijiye
Not explained properly in end.
Friends😅
Sir apka ista id
Direction of rotation is not correct.
Not cleared
Thank you sir
