sir can you please explain that why we considered the bottom tangent line instead of taking the distance from top of vessel?
We appreciate your technical approach towards basic concepts Saipriya.
See what happens when you consider top tangent line and if you are dealing with sub cooled liquid then you will get more hydrostatic pressure at top tangent line and your NPSH value may come out positive but when you draw the liquid from tank it's level will drop which causes drop in hydrostatic pressure this results into decrease in NPSH value and one point may come when it will become negative and pump may cavitate.
But when you consider bottom Tangent line in this case your hydrostatic pressure is minimum below which it will not fall and if you calculate NPSH for this level and adjust tank elevation and pipe size accordingly then it will be very conservative case and your NPSH will never be negative.
Hope we understood your question and tried to answer it correctly.
Thank you.
Enjoy learning. All the best 👍

@@PayosAcademy Hello sir.. if suction line might be from one side of tank and not from bottom but still above the pump center line then in that case how to consider the Elevation from Suction vessel from grade and Vessel low low liquid level? It will be still the same as shown in here?
Good question Amruta.
You are right, you have to consider height from grade to low low liquid level.
Because see your low low liquid level will be anyways above the tank nozzle, so your pump will get flooded suction.
And considering low low liquid level will be the worst case possible for NPSH calculations instead of high or normal liquid level.
Hope we understood your question clearly and tried to answer it correctly. If not please feel free to get back to us.
Thank you.

Shut off head formula varies in excel and initial explanation of formulas ..
In excel shut iff head = max suction pressure * 1.25 + diff pressure
While at initial explantion
Max shut off head = max suction pressure + (1.25 * diff head)
Can u pls give the crct ans
Sir at 19:41 the formula for converting pressure to head should be (deltaP *10.2) / S.G. Correct me if I'm wrong
Plz Make a video on p&id
Thank you Nitin. We will definitely try to make video on p&Id as early as possible.
Sir in differential head formula SG should come in divide not in multiplication..?
Yes you are right. We need to update it.
Thank you 👍
Sir,
If I am using pump as reflux and my column in vaccum pressure 720mmHg then what will be my discharge pressure secondly what will be my reflux drum pressure atmospheric or vaccum please answer I am supposed to line size for my company project and getting confused
Please help
Very good question Muneer. We will surely try to make a separate video on this.
Coming to your question. You need to consider whatever your discharge pressure at actual, and you need to convert it in to absolute pressure so that you will get positive value of discharge pressure. Then continue with same calculations.
Hope we understood your question clearly and tried to answer it correctly.
If you find any query please feel free to get back to us.
Thank you.
Sir please cover the video on control valve sizing
Thank you Muneer for your valuable suggestion.
We will upload our next video on control valve sizing.

Sir please can you explain, minimum circulation line concept, and how we consider it in pump sizing also.
Thank you for your valuable suggestion Abdul.
We will surely cover this important topic in our upcoming days.
Till that please find below response for your question-
Minimum circulation line is bypass line either in source tank or suction of pump. This is done so because every pump has minimum flow rate that pump vendor will give or mentioned on pump curve. Also if we throttle valve that will reduce flow and increase head to overcome extra head we provide minimum circulation line.
Hope this will help you.
If not please feel free to get back to us.
Thank you 🙏

why head is in m but not in Pressure ?
The pump head or discharge head of a water pump is a measure of the power of a pump. The greater the pump head, the greater the pressure that the pump can generate. This statistic is measured in meters (or feet) and is calculated by placing a tube on a pump’s discharge and measuring the maximum height to which it can pump water.
You are absolutely correct Saipriya. We want to add in your answer-
Head is independent of liquid to be handled but pressure depend on fluid density.
Pump manufacturers performs their test with water and develop pump curves if they want to consider pressure then they need to perform test for all fluids instead they perform test on water and develop head vs flow cuve which can be used for any fluid.
Thank you.
All the best. Enjoy Learning 👍

In pump shutoff head calculatio How 4m of water head converted to 3.924 bar, it should be 0.3924 ? Please explain
Yes shreyas. You are right.
You need to update formula with 100000 instead of 10000 in the denominator.
We have pinned this in our comment.
We will be happy to hear more from you.
Thank you. Enjoy learning 👍
Sir can you explain me
Why we take 1.25 in calculation of shut off head I want to know that from where 1.25 come in shut off formula
Shut of head = max suction pressure + ( 1.25 * Diffrential head )
Very good question Nikhil. During FEED stage engineering we don't have exact hydraulic calculations which may change during detail engineering. That's why we consider this formula on conservative side.
This formula may vary from company to company.
Also in detail engineering you get pump shutoff from pump curve.
Hope this will help you
Stay tuned with us

D to B is conservative case hence we calculate pump discharge accordingly. But for C to B and E to B we have to kill excess pressure through the control valve. Correct or not please reply.
Yes absolutely correct. We have considered the same example in our control valve video.
Please go through it.
Hope you like it.

I think the formula added for pressure drop/100 m in the line sizing sheet is slightly wrong.
Should n't we club 2*9.8*Diameter in the formula ?
In the current situation while evaluating the formula, the value after multiplying d29,d16 and d33 square with 100, it's getting divided by 2 followed by multiplication with 9.81 and diameter. Please check.
Thank you Jayesh.
We have updated the formula and for new viewers information we have pinned the comment.

Calculation of hydraulic power in KW is Q x Differential pressure/36.71..then why E19/1000 is done in calculating Hydraulic power cell?
Yes you are correct.
Sir aap bol rahe hain ki per 100 m pressure drop 0.45 bar hota hai agar es value se calculate krte hai man lijiye 1700 m ki line hai to pressure drop 7.5 bar ho gaya jabki pump ka pressure according to design 4 .7 bar hai or head 47 m hai agr itna jayeda pressure drop hoga to fir jahan discharge ho rha hai waha ka pressure zero ho jayega jo ki sambhav nahi hai
Per 1000 m per kahte to sambhav hai
Per 100 m is correct. 1700 m is not short length if you consider max velocity you will require 7.5 bar pressure, and if you want to reduce it you can increase line size.
Hope this will help you.
Sir where is sheet
Please share your email id on our LinkedIn or Instagram. We will share the excel sheet with you.
Enjoy learning 👍
sir why discharge velocity is maximum 3.2m/s??
It is based on good engineering practice. As if you increase velocity pressure drop will increase and if you decrease velocity line size will increase in both ways cost will increase. Every company has different range based on fluid they are handling and this range will give optimum pump size and line size.
Hope this will help you.
a rectangular water tank each 8 meters long, 6 meter wide, 4 meter height is filled with water calculate the quantity of water in the tank. in fire fighting pump connecting head 30cm height connecting the bottom and having discharge of 1620 lpm for how much time fire fighting can be done
Instead of directly providing answer I will provide you the steps-
1. Calculate volume of tank (L*B*H)
2. Divide volume with pump flow rate. If flowrate in m3/hr you will get time in hrs.
Hope this will help you.
Stay tuned with us. Enjoy learning 👍
Sir please share the link of excel sheet
Please share your email id on LinkedIn or Instagram 🙏
- centre line kay ahe?
Pump centre, because the pump suction line enters the casing centre.
Head meter main kyu lete hey bar main kyu nai??
Head in meter is independent of specific gravity of fluid bud pressure in bar is dependent on specific gravity.
