Thanks so much for posting!

[@GymPeter]

Thanks for your video
I have a question. Why did you use the HTFS method instead of Crane??
I did some simulation and different pressure drop value was derived between HTFS and Crane.
Do you have any idea of which method is correct?

[@Sabrina-le6im]

how to know vapor fraction if the material is saturated steam?

[@jesusaldanarivera5899]

Can you simulate a gas leak?

[@nagaraasu]

Thanks for your video.🙂🙏

[@Processengineeringguy]

Most welcome 😊

[@kamalpakdaman4230]

Good Job Budy.

[@Processengineeringguy]

Thanks

[@pascaltorvic6246]

That was good, thx

[@Processengineeringguy]

Glad you liked it!

Keep it up man@@Processengineeringguy

[@kmh6578]

So 7319 kg/hr is choked flow condition, the max flow possible?

[@Processengineeringguy]

7319 kg/hr is the max flow can be possible

[@nagaraasu]

Shall i use this orifice sizing to determine Pipeline leakage rate. for an example, leak hole size is 50 mm (assuming this is orifice size), and upstream conditions are known. Downstream condition is open to atm. Is it correct approach to estimate leakage rate.

[@Processengineeringguy]

Yes you can and the approach you explain above can be used

[@nagaraasu]

Thanks bro.@@Processengineeringguy

[@rohandamle4929]

How did you take throat dia 10mm??

[@Processengineeringguy]

No specific reason, just take random size and then you can fine tune as per your process requirement

[@dcetian85]

What will I for reverse flow condition if i am sizing for nitrogen?
