Centrifugal pump sizing and selection in six easy steps

[@marciochao4849]

Best explanation on youtube i have seen so far.

[@eduXinsight]

Thanks 😊

[@Parth_s48]

Wow sir!!! This is the easiest accurate explanation of centrifugal pump I've seen so far!!! 💯 Hats off to you.

[@sauravkamalmedhi6008]

Thank you so much for this video..Educators like you are the real teachers

[@eduXinsight]

Thanks for appreciations Saurav.

[@muhammadfarhan2440]

Great video explaining pump sizing

[@adepitanbero5345]

This is a very clear illustration of how to go about pump sizing. Good job.

Simple and clear explanation... Thank u sir.. Keep doing

[@vengatcud]

Very nice video.... Crystal clear explanation you have given. Thanks to you...

Best video

[@akreenwilliams2920]

Wonderful video 👍

[@m.shahidrao4487]

Very well explained. Thanks 😊

[@user-ex4sd5wd6s]

Well explained 👍. My question is, if we are having closed tanks, where do we take our points on bernoulli equation (Top of the tank or at the bottom of the tank or at the exit of the tank). Additionally, will it be also considered as atmospheric pressure?

[@ishakekrem8113]

The video is amazing, but I think at 15:15 according to the drawing, in the calculation of NPSH available Z must be negative too since the suction is made from a lower altitude, this formula is valid if you have the reservoir above the suction level.

[@eduXinsight]

Thanks for your appreciation and pointing out the mistake 🙂

[@mukulraipure]

Yes, I'm also have the same query

[@sumeetarya5635]

APRAISING WORK ,

[@eduXinsight]

Thanks 😊

[@ahmedahmed-lf5mi]

wonderful job thank you

[@lonelymickey]

I have few questions here: So if we have selected the efficiency based on the curve and calculated our power input? what is the difference between power input and the power consumption in pump curve? Some pump curves gave us the horsepower too. In this case, how shall we determine the efficiency and determine which pump to go?

[@mehrafarinemoradkhany]

wish I had found you earlier

[@prajeeth.k]

Nice explanation. Could you please explain vapors pressure formal with unit. What is A -B /c+T. What is a what is b what is c and T with units.

[@eduXinsight]

It's Antion equation, and you can find it in any thermodynamics book with details

[@prajeeth.k]

@@eduXinsight thank you. Would you mind sharing the real time project pump selection & calculations. Your teaching is very good and we support you and look forward learning from you. Thank you.

[@hamdanifire7294]

excellent thanks sir

[@chemicalengineer1985]

Good explain

[@rachmanhardian6858]

if you want to explain something using any equation method, please describe each parameter unit used in the equation, either for imperial or metric system, that will be a lot of help

[@eduXinsight]

Thanks for the suggestion

[@ihabghazali8619]

in 12:52 , do you mean, dynamic head = static head TH ( SUCTION AND DISCHARG)+ straight friction head + fitting friction head ?

[@ihabghazali8619]

is superficial velocity a constant factor for water? i

[@harisenafebriadi]

Thank You sir, maybe you can share link of presentation also,,

[@kazmcancalskan1936]

In introduction, You have said that you encountered the differences between theoretical knowledge and practical application in sizing&selection about centrifugal pumps at industry. What can we mention more about these differences that you felt? Can we say that the video is more connected to practical application experience of yours or the opposite more theoretical?

[@eduXinsight]

More practical ones

[@rifkiamar106]

Do you have a book to read about pump design?

[@eduXinsight]

No I don't have a specific book for that

[@shyamsundarkannan7919]

where can we find the K valve for fittings? please let me know

[@fadyelrahib670]

and how can i find the velocity without selecting the pump????????

[@eduXinsight]

Velocity in pipe or what?

[@fadyelrahib670]

@@eduXinsight yes

[@eduXinsight]

@@fadyelrahib670 Flowrate (m3/s) divided by pipe crosectional area (m2), it gives you velocity in the pipe

[@fadyelrahib670]

@@eduXinsight and how to get the flowrate?

[@eduXinsight]

@@fadyelrahib670 it is the design parameter and you have to decide for particular application how much flowrate should be

sir what is this A B AND C IN log pv equation?

do u have pdf for this video ?

Do you have the notes for this? Can share?

can i have a copy of your chart sir?

sir what is the value 2.3?

[@ihabghazali8619]

ME TOO ASK

[@Abhijeetsingh-ql5il]

What will happen pump is run much below its rated head like outside the performance curve, other than low efficiency. Why cant a pump run at zero head

[@eduXinsight]

it is an indication that the pump impeller has damaged if all other pump parts are ok like sealing, bearings, etc. Regarding the second point, there is no point to run at zero head. But if you run at zero head pump will go on cavitation and damaged and pump efficiency will be close to zero.

[@Abhijeetsingh-ql5il]

For example if i have a 25m3 @ 12 kg rated pump and i put it in line where required pressure is only 5 kg. How will my pump perform.. will i have to throttle the pump... And what will happen to required npsh

[@eduXinsight]

@@Abhijeetsingh-ql5il do you want the same flow rate 25 m3?

@@eduXinsight no i want max flow rate that is possible. Head around 4 to 5 kg is acceptable
