Pressure Drop in Plate Heat Exchangers

A short conversation about Pressure Drop in Plate Heat Exchangers, what it is and why it is important

[@MarkLucas]

The Darcy-Weisbach correlation you use to relate Delta(P) to velocity is more tailored to pipe flow. Works great for a shell-tube, not sure how valid it is for a PHE. Are there more suitable ways to theoretically validate pressure drop for a PHE?

[@gert_kruger]

Is there simulation models available to simulate pressure drop vs flow?

[@md.mahbuburrahman1403]

Thanks for uploading such an important video illustrating pressure drop in chevron plate heat exchanger.
Distribution partner? I heard more times but I listened the same every times.

[@heattransferchannel8474]

Yes, :-) I mispronounced that a few time, let's call it a test to check if people pay attention! :-)

How heat exchanger do for phosphate?

[@dianheatexchanger547]

Thanks.. 👍

Would like to request for phe leak test overview

Hai sir how are you? I hope doing well
Sir we are mostly doing plate heat exchanger servicing. It’s very hard to loss and tighten the plates sir we are losing and tightening manually only sir. Is there any equipment and tool for tightening plate heat exchanger

[@heattransferchannel8474]

Yes, there are either pneumatic or electric tools that can be used to loosed and tight heat exchangers, and we use them regularly.

[@Khabbazhadi]

thank u sir for ur elaborative video on PHXs. i do have a question though. based on what u said, if i want a 2" connection size, is it better to use a plate with a 2" port size at max, or use, for instance, a 4" port size plate and reduce the connection down to 2" ?

[@heattransferchannel8474]

if you have a 2" connection, I would recommend 2" port heat exchanger. Every time that you reduce the size of a pipe you have some undesirable pressure drop. Does it make sense?

[@Khabbazhadi]

@@heattransferchannel8474 it does. but just take port and connection pressure drop into consideration, what's the difference between '4" plate reduced to 2"' and '2" native plate size', pressure-drop wise?

[@Khabbazhadi]

@@heattransferchannel8474 im really interested to learn more from you sir and use more of your wisdom and knowledge in heat exchangers world

[@heattransferchannel8474]

@@Khabbazhadi Well, if you have 4" pipe because you need that flowrate, the moment you squeeze it down to 2" you will have significant pressure losses... how much depends mainly on the flowrate.... so, if you have 4" piping the best possible solution is to have at least 4" ports...

Hi sir

[@exofura]

basic stuff, great presentation but, most people prefer ignorance...
