Sir I have problem that in book overall efficiency is equal to manometric efficiency ×volumetric efficiency ×mechanical efficiency. And you told different...so which one is write?
sir values put kr k btayn i still confused about pressure head . mary pas kuch value hn kia in sa head find ho jay ga dia 346 cc 480 Q 1800 usgpm H 115 feet n 1450rpm or moter ka data ha v 400d hz 50 kw 75 rpm 1486 A 135 cos ø 0.84
Alex Myladoor actually there’s a lot of confusion going on even in the books. If you calculate the unit of (Vw2.U2)/g then it will come as meter. And also (Vw2.U2)/g is work done per second per weight flux. Not just weight. Weight flux is (kg/s)(m/s^2)
Sir very nice. Sir agar aik 1/5 hp centrifugal pump 30 feet hight 1" pipe k sath pani throw karta he to kia horizontaly 400 feet tk same velocity aur GPM k sath deliver ker sakta he.? Respected sir please guide me Thanx a lot.
Very good expiaination Sir. I have tried to watch all centrifugal pump videos as you suggested in perticuler order I have one request. I have heard that CF pump efficiency is maximum around 80%. Please make a video on why pump can not convert all shaft power to head generation. I am not talking about pipe losses. Also explain efficiency curves and various main and operating characteristics of CF pumps
In mechanical effort formula...You are multiplying impeller work done that is in energy per unit weight with weight making it in joule....... But dividing it with the shaft power which can be in watt.....which is wrong....So I think it impeller work done which is Vw2*U2 whose unit is KJ/kg shud be multiplied with mass flow rate making it in watt...... Then it shud be used in mechanical eff formula....... Pls reply if anyone thinks that I am wrong.......
bahut acche se bataila guruji...kul samaz me aa gayal.....baba vishwanath aapka bhala karen
Some of us unable to understand Hindi... please do the complete lecture in English sir...hope you understand ✌️...Very informative...Thanks
each video of yours on pump is very nicely explained. thank you
What is dynamic head
U taught manometric head very easily nd accurately.. ❤️
NPSH pump manufacturers define karke dete he ya hame khud karna hota he? Agar positive suction he to kya cavitation hoga?
Couldnt get it...what is W2 and u2?
Awesome Work😍
The effeciency plotted on charactristic pump chart , is manometric effecirncy or mechanical effeciency or overall efficiency ?
Very good
W is the weight of what?
nice explanation
sir vw2u2/g wale formula kese aya. apne description m b nhi dala h.?
Very informative 👏🏻
Useful videos and nice teaching
Sir No Volumetric Efficiency added in Overall ?
How to calculate pipe size for suction and delivery?
very nice explanation
Sir apne hindi me bataya bahut hi dhanywad
Sir i cant understand these effeciency equations.,any simple way to understand these equations??
may you please use English when you explain
otherwise thank you, your videos do help
usho nje Buhle
what Vw2 and u2 means??and volumetric efficiency too
Sir Im telugu.. How can i understand ur hindi.. Pls use english..
First you are indian
nicely explained
Thanks sir
Nice method.
Plaese share some reallife example based numericals
Sir I have problem that in book overall efficiency is equal to manometric efficiency ×volumetric efficiency ×mechanical efficiency. And you told different...so which one is write?
The final equation will be same.
sir values put kr k btayn i still confused about pressure head .
mary pas kuch value hn kia in sa head find ho jay ga
dia 346
cc 480
Q 1800 usgpm
H 115 feet
n 1450rpm
or moter ka data ha
v 400d
hz 50
kw 75
rpm 1486
A 135
cos ø 0.84
sir in the last video, (vw1u1)/g IS the W.D per sec per weight.. so then why should we multiply another W? at 8:10

Heyoo, we need one in full English please. I have followed the series up to here only for it to change to Hindi.
do this in english..it will be a great help for worldwide
Volumetric efficiency???
kindly share the link of calculation of work done by impeller
h basanta sharma
Sir very nice.
Sir agar aik 1/5 hp centrifugal pump 30 feet hight 1" pipe k sath pani throw karta he to kia horizontaly 400 feet tk same velocity aur GPM k sath deliver ker sakta he.?
Respected sir please guide me
Thanx a lot.
Can you please solve any problem based on Head or elaborate the formulas for Manometric Head
What is g
Sir but volumetric efficiency
Sir plz tellme Volumetric efficiency
Please do use English throughout.
Maximum efficiency kya hota h sir

All vidio can be provided time to time ..
Sir in your subscribers like me can't understand HINDI
So plz continue in English.....
We miss some important points otherwise
suddenly in tamil haahahhaaha but thank you so much
Rou Lee not Tamil. It’s English + Hindi ! 😁
Water at 60feet in ground ...mono block motor are work are not
Pls. speak english until the video finish
english subtitle
Please explain in complete english sir because I dont know hindi
I hate it when half of the video in English and the other half other languages, Make up ur mind!!!
speak English!!!!!!!!!!
What happened to speaking English????????
Standard language please...
RK bansal chhap di
rk bansal copied
dislike for being in hindi🤷♂️(actually not suggesting that in title)
