Pressure Drop in a Grooved pipe

[mattoverduin]

The airflow inlet into a 1" grooved copper pipe is 270 cubic feet per minute. The pressure is 105 psi, at an inlet temperature of 30 F. The copper tube is 1 ft long and is twisted.

How do you calculate pressure drop through twisted tubes?

Take a glance at the attached paper: you'll find a correlation for pressure drop in twisted tube.

Hope it could help

Thanks,

I should've been more specific. The pipe is corrugated copper (little ridges on the surface).
