Pressure Drop Difference in Smooth vs. Convoluted Hose

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

My reference says use e/d = 0.2625 for 5/8" corrugated flex hose.

Good luck,
Latexman
