Hi mam In this seminar, initially you selected the velocity of 2.5 m/s and then calculated the dia which resulted about 206 mm. Then you selected the dia of 203.2 mm , then calculated the velocity which resulted about 2.57 m/s. Finally you finalized the dia of 203.2 mm with 2.57 m/s dia. Now i have doubt how you selected the previous lowest pipe size as 203.2 mm. And how to you select the final dia for calculating pressure drop? This is my doubt kindly guide me.
RE calculation- the formula after changing absolute viscosity to kinematic, either kinematic with density or only absolute viscosity shall be there...no coexistence
Thank you, I am a design engineer and I want to make my own choice on piping when designing an industrial plant, now that I have a basis I can easily apply for Piping.
Thanks for best explain. Please provide calculation of water supply pipe size with pressure and Velocity at very from floor to floor for high rise building.
You are right but under same situation , different dia pipe will have different resistive force so optimum pipe size for perticular pressure ( which have relationship with temperature) also higher the pipe size higher the load .so we have to go for optimum sizing by considering appropriate velocity.
Hi, Mam Can you please help I have to design ferule size and service pipe size from main municipal water connection to a housing complex 96 Flats Total water demand 96×5×135ltrs Size of Main municipal line is 300mm dia Distance from our UGR to main line is 30m Pressure available in main line is 12PSI. Please explain the method and formula to calculate tapping size(ferule) and service pipe size for our complex.
By calculation we got D =206mm but if you see standard pipe size where OD is fix . so we can either with 10in 250NB or 8in 200NB. So here we have selected the later (previous) size that is 200NB and 203.2mm OD or 8in pipe. I hope its clear now...
how do you got the previous lowest pipe size and some mistakes in velocity validation with lowest pipe die and pressure drop how do you got new (viscosity value) please explain it
I am trying to design a plumbing main water supply pipeline, which supplying a water by gravity system (From over head tank). The building consists of 14 floors. In one unit I have three fixtures. (Wash basin, Bathroom & WC). Would to please guide me the steps of the calculation of pipe diameter required. I am also trying to devide pipeline in two zones. One is 1st to 14th or 7th & another is for 8th to 1st or Ground floor.
Question: There are two parallel suction pipes 560mm connected to 2 pumps and then deliver side there is common header to which on delivery pipe is connected 710mm. When both pumps run simultaneously each pump draws 1500m3/hr . In 710mm flow will be 3000m3/hr. Suction side loss 5m each pump. How will you calculate delivery head for each pump for selecting the pumps. Will the delivery pipe friction head loss be distributed among two pumps? . What about delivery side elevation?
Thanks mam for this amazing vedio , but I am little bit confused in last that if available pressure drop is less than 0.3983kg/cm2 than how liquid flow is obstruct or not possible and if liquid flow value is more than 0.3983kg/cm2 than how it be possible. How we can relate this value to identify that the flow is possible or not ???? And how it relates with pipe size dia. Pls give u valuable sujection .......
These are the set range based on years of years lesson learned in industry. Higher velocity Increases errosion of pipes, vibration. If you go below the velocity then there can be deposition. Thank you for asking this. I should have explained this in video.. please subscribe if not. Keep supporting and keep learning♥️
Hi.. this is a very nice information. Can I use this to size the transfer pump pipe size of water and sump pump pipe size for grey water? I have the discharge known from the total fixture units
Very useful lecture.. only one thing doubting me about the last equation of pressure drop, did the used one applicable only for gas? Our fluid is liquid
Im student, I have question I need to know how i can find the length of pipe required in order to keep 100 Liter water saving inside pipe, For example boster pump is power 1hp
Pipe diameter is 1 in, how I know the length of pipe required in order to keep water inside pipe, and pressure, and how i can check is the 1 hp will be enough Or I need to increase, please help me
this is such an informative video!!! Cant find like this anywhere. I have one doubt: what do u mean by available pressure drop at the end of the lecture? And how to calculate it when comparing our calculated pressure drop with it.
In my understanding, we have the pressure values at 2 ends of the pipeline. The difference of these 2 values is the available pressure drop. You can refer the beginning of the video to understand more.
My whole 1 week prepation explain in 12 minutes
Waah great teaching ❤️❤️❤️
Your calculation is wrong please re check
At 10:52 that you calculate the fluid velocity I can't understand why 300/(3600 * 0.32412) = 2.571m/sec. In my calculations is 0.2571m/sec
Wow! Excellent lecture! May I know the source for the recommended velocity range?

it is in the range of velocity..
and standard dia of 8" pipe is 203.2.
which is validated by 2.57m/s velocity

Yeah i got it thanks.
@10:20, you mentioned previous lowest pipe size. Please explain what it is.

Hi , what is the source of velocity by pdf?
tank you very much for shared this lesson.
Madam from where u have taken the velocity table can u share it,it's helpful to me
Pipe dia increase karne kya hota hai..step by step...ex. 150....200....250...300
suppose i have a liquid with density 0.789 kg/lit at 25 °C so how i go for velocity assumptions
WHY USED GAS EQUATION FOR LIQUID WATER.
FOR WATER HEAD LOSS REQUIRDD.
How about calculating mach number for a pipe size by iteration
What is “available pressure drop”
Excellent work.....but from which standard would we get this recommended velocity that you have shown in a table
Shell DEP and API RP14E
Wow it's amazing description ...
Very useful information
Your overall video is excellent but I have a doubt on how does decreasing pipe size would minimize flexibility problem in pipe kindly explain it
For calculating Pressure Drop should be considered frictional losses via Tees, Elbows, Valves and fittings.
Thanks for best explain. Please provide calculation of water supply pipe size with pressure and Velocity at very from floor to floor for high rise building.
Thank you for your detailed explanation. 😀
Because flexibility problem is taken care by making loops in the pipe so how will you justify your statement at 8:30 min in your video
You are right but under same situation , different dia pipe will have different resistive force so optimum pipe size for perticular pressure ( which have relationship with temperature) also higher the pipe size higher the load .so we have to go for optimum sizing by considering appropriate velocity.
How u got roughness factor.
How viscosity at what temp.
Why not c.brookes equation?
Very comprehensive and beautifully explained cheers
Than you.could you please prepare a video for restriction or if ace sizing
You mean restriction orifice ?

Thank you Uday... You will not believe its our First super stickers... Thank you once again🙏🏻🙏🏻
Can you please send line size & pressure drop calculation for steam lines
Where from previous lowest pipe size pls.. I’m lost
Nice lecture, If the pipeline having bends, how can we calculate the pressure drop.
why are you replacing P(roe) with 1/v(niu)
no.. its p(roe) replacing with u (meo)/ v(niu)
@@PipingMantra Yeah but then the numerator should've become M(meu) squared instead of just M(meu), right?

make a video on types of pipe and difference between tube and pipes in details...
Sure
Picture and writing not very clear..
can you share the source of the table plz?
Pls give a video of how fluid velocity & pressure affect in a pipe line & its requirement of different pipe sizes with numerical
Diameter calculation wrong
Question: There are two parallel suction pipes 560mm connected to 2 pumps and then deliver side there is common header to which on delivery pipe is connected 710mm. When both pumps run simultaneously each pump draws 1500m3/hr . In 710mm flow will be 3000m3/hr. Suction side loss 5m each pump. How will you calculate delivery head for each pump for selecting the pumps. Will the delivery pipe friction head loss be distributed among two pumps? . What about delivery side elevation?
Yes will be distributed between the pumps as the flow is fixed
What about velocity of water..
Thanks mam for this amazing vedio , but I am little bit confused in last that if available pressure drop is less than 0.3983kg/cm2 than how liquid flow is obstruct or not possible and if liquid flow value is more than 0.3983kg/cm2 than how it be possible.

Thank you madam it helped me
hi sir, thanks- is it used for hydraulic system?
Yes. It is one of the methods however there are other methods as well

Well explained. Topic for next video valve sizing and selection
Sure
horizontal 1950 ft straight line of 3'' dia ,40 taps X 15 lpm =600 lpm what should be the tottal head
Why we shouldn't increase velocity of a fluid more than allowable velocity? What will happen if we increase?
These are the set range based on years of years lesson learned in industry. Higher velocity Increases errosion of pipes, vibration.
If you go below the velocity then there can be deposition.

PPR pipe
Q=100 LITER PER S
V=2.5 m /s
where did u get the list of recommended velocity range? how about for natural gas and LPG?
The calculated area for d=203.2 mm should be 0.0324 m2. this value should be corrected.
She mixed up the diameter and radius. D is something on the left hand side then used it as a radius to calculate area on the right hand side
Nice
