Pressure Drop Difference in Smooth vs. Convoluted Hose
Pressure Drop Difference in Smooth vs. Convoluted Hose
(OP)
Does anyone know how to compute the pressure drop across a convoluted hose as compared to a smooth bore hose using air as the working fluid?
I've been using Darcy-Weisbach for the smooth bore hose, but can't find any information about pressure drop in a convoluted hose.
Both hoses in question are 5/8" ID, same flow regime (same inlet pressure and flow rate), and the same length.
I found some good ideas on thread378-101803: Calculating Line/Pressure Loss Across Expansion Joints, but the equations were slightly confusing and any better data would help.
Thanks
