Valves and Fittings Pressure Drop - Darby 3K Method - Flowmeters
(OP)
Good evening,
Does anyone have any information on the Darby 3K method for the pressure drop due to valves and fittings pertaining to flowmeters of various types. Been unable to obtain K factors for these with this method.
Any help appreciated.
Best Regards,
Stuart

There are so many flow meters and so many sizes, the 3K Method would require a Herculean effort to characterize the lot. If your vessel has a limited number of types/sizes, it may be doable. Do any of your preferred vendors offer downloadable software? That's the not so recent way of doing it. It may be worth an e-mail.
Good luck,

Take your point about the number of Flowmeters, that'll explain why I haven't had any success. Will just get the values for the ones we currently use and add them in, atleast it's a start.
Thanks alot.
