Highly viscous fluid
Highly viscous fluid
(OP)
Hi,
Do you know any standard/recommended practices about sizing relief valves for highly viscous liquids (9000 cP)?
Are API 520 or ISO 4126 applicables?

I have noticed API proposes an iterative procedure to determine the required orifice area. But in my case, i cannot find a solution. Each time i increment to a higher standard orifice size, the Reynolds number decrease and so does the Kv coefficient. As a result, i always need a bigger orifice size....until i reach the point where there is no higher standard size available.
Another point where i am lost is that the Reynolds number decrease as the orifice size increase...strange?
FYI
Pset=18 barg
total backpressure=1.7 barg
T=50 degC
Q=19 L/min
G=0.89
mu=9000 cP

by Randall W. Whitesides, P.E.. Its all over the net....I couldnt dowload the link either.

But do you know where do those correlations (Kd, Kv, ...) come from? Are they from DIERS?
