Verification Case 24

View Model     Problem Statement

PRODUCT: AFT Fathom

TITLE: FthVerify24.fth

REFERENCE: Michael R. Lindeburg, P.E., Mechanical Engineering Review Manual, 7th Ed., Professional Publications, Page 3-19, 21, Example 3.19

FLUID: Water

ASSUMPTIONS: N/A

RESULTS:

Parameter	Lindenburg	AFT Fathom
Head loss (feet)	51.6	51.53

DISCUSSION:

All input was provided explicitly by the problem statement.

Lindeburg pulls the friction factor directly from the Moody chart, while AFT Fathom uses the Colebrook-White equation to iterate for friction factor. Both methods result in a friction factor of 0.0195 if the friction factor is rounded to 4 digits.
