Orifice BETA RATIO limit | Why does it EXISTS !!
HTML-код
- Опубликовано: 30 июн 2024
- Orifice Beta ratio is the ratio of Orifice bore to Pipe ID.
A beta ratio of 0.4 signifies that the orifice bore diameter is 40% of the pipe inside diameter
In this video we would learn the API MPMS graph and why do we have a range of beta ratio between 0.3 to 0.7

Keep learning and keep growing in your career !!! ✔
Truly I like the way you explain it. You use a simple language which can be understood and remembered forever by anyone. Great! keep doing!
Sir bahut bahut best video❤❤❤ love from India 🇮🇳🇮🇳🇮🇳
Truly it's like what I learn in 6 months in a semester you teach more than that in like 10 mins😂❤❤❤
Great video sir🎉
You have explained and narrated very well.
Perfect video, finally a good video in English language
You are really doing a great job Sir, Very Informative Videos.... Lotsss Of Thanks To You For Motivating Us All To Achive Something Greater & Bring Betterment In What We Love To Do..... Lovely Branch Instrumentation 💖✨️💐💐🙏🙏🙏 Thank You So Much For All Ua Efforts Sir💖✨️💐🤲💐🙏
dude your videos are amazing and great to watch. thanks a lots.
Glad you like them! 😊 You words inspire me to create more such videos !!
Thanks for the excellent explanation
Nice Video bro.
ISO 5167 defines range of 0.2 to 0.7 . However while engineering we consider 0.3 to 0.7 as safe limits. But it is important to also consider straight lengths as your uncertainty and accuracy depends on straight lengths as recommended while sizing.
ISO 5167 has a table mentioning straight run recommendations from beta ratio of 0.2 to 0.7 .
Yes !! Very true ... Good point I will also make a video on Straight run recommendations in ISO 5167 and how it can affect accuracy ... Thanks for sharing 😊
I want ISO 5167 calculations design book.
Beta ratio tables also I need. Where I will get
Pls help me
Great explanation
Could you please make a vedios for valve selection and instrument selection in oil and gas industries
Like what valve and instrument need to install in pipeline and equipment
Thank you.
Hi Asad , can u make videos on various flowmeters
Hello sir, very good presentation. what is the relation between beta ratio and straight length requirement?
Great Useful information Asad 👍 maybe you can also cover the main factors affecting orifice DP flow meters’ accuracy ✌️
Thanks 😊 !! Sure that is an important topic with regards to Flow meter's accuracy and a lot of parameters need to considered like turndown will surely make a video
Good going Asad.
Make a series video on Datasheet Prepartion. Particularly TE+TIT+TW, FE+FT etc
Sure Vitthal Rathod 😊
Thank U Asad
Most welcome 😊
Really it is a good explanation
Can we have a video on Nema standard
Thank you , and can you elaborate the exact topic, it would be very helpful !!
Please make some videos on control valve sizing , how can we size the trim set .
Which type of plug, steam set is used where
Sure , Will try to cover more control valve topics, Thanks for your request 😊
Thank you
Most welcome 😊
Sir, i want to calculate downstream pressure after RO, pls guide me how can i do it?
On 4.35, if we keep a 'very high' beta ratio then we will not be able to maintain the allowable pressure drop limit...
I think low beta ratio will create more pressure drop.. & then it will difficult to maintain allowable pressure drop. .. please correct if I am wrong
what is uncertainty?
is it possible to use a orifice beta ratio of 0.2 on a 2 inch pipe? ( interview question) some documents saying that it can be between 0.2 to .7
It is not recommended, however if the uncertainty and accuracy at the Beta ratio of 0.2 is acceptable and there is no other option feasible then it could be considered.
Example : A Colleague working for NASA had shared that they had used a orifice with 0.2 Beta because that was the only feasible option for their application and the engineering team was ok with the accuracy and uncertainty.
But as a rule of thumb this should be avoided 😊
@@AsadPassionateEngineer thank you
Is this beta ratio standard applicable for RO? or can be less as no measurement?
Yes 0.3 to 0.7 criteria is stringent for Orifice, for R.O this strictness can be relaxed 😊
❤
glad you liked it !! 😊
Where can we get orifice calculator.
Like bore and do calculations
API MPMS standard has this thickness table. Hope it helps !!
I want ISO 5167 calculations design book.
Beta ratio tables also I need. Where I will get
Pls help me
I am planning to make a video on that, Hope it helps
