Flow calculation through valve and hose
Flow calculation through valve and hose
(OP)
I need to calculate the flow through a 3" valve and a length of 3" hose...I've done hundreds of these for flow through rigid piping, never anything through a hose.
Does anyone have any empirical data for flow through hoses? It will be strewn such that the bend radii are as large are possible. Were it pipe I'd do an fl/d*v^2/2g with a known f...I have no idea what realistic friction factors for hose might be, .02? 0.03? Reasonable estimates for total K given some random bends?
Thanks for any help!

Here's an example of what I'm talking about (involving lay-flat hose):

I've found similar tables in the past for rigid SS hose.
A "quick and dirty" rule of thumb is that pressure drop in hose is approximately 3 times that of steel pipe.
