Verification Case 79

View Model     Problem Statement

PRODUCT: AFT Fathom (with ANS Module)

TITLE: FthVerify79.fth

REFERENCE: Robert W. Fox and Alan T. McDonald, Introduction to Fluid Mechanics, 3rd Ed., 1985, John Wiley & Sons, Example 8.8, page 377.

FLUID: Water

ASSUMPTIONS: N/A

RESULTS:

	Fox & McDonald	AFT Fathom
Minimum Diameter	6.065 in	6.065 in
Nominal Size	6 inch	6 inch

DISCUSSION:

The AFT Fathom pipe material library does not have drawn aluminum pipe so steel pipe size data was used. The roughness model was modified to use a relative roughness of 0.00001, which is representative of drawn tubing.  With this setting, the results for nominal size matched exactly.

The automated sizing was discrete with the objective set to minimize flow volume.
