PRODUCT: AFT Fathom

TITLE: FthVerify30.fth

REFERENCE: Crane Co., Flow of Fluids Through Valves, Fittings, and Pipe, Technical Paper No. 410, Crane Co., Joliet, IL, 1988, Page 4-4, Example 4-7

FLUID: SAE 10 Lube Oil at 60F

ASSUMPTIONS: N/A

RESULTS:

Parameter	Crane	AFT Fathom
Volumetric flow rate (gal/min)	118	121.4
Velocity (feet/sec)	5.13	5.267
Reynolds number	1040	1095

DISCUSSION:

Because of the high oil viscosity, there is laminar flow in the pipe. As discussed in Crane, this is an iterative problem. Crane performs one iteration, while AFT Fathom performs numerous iterations. The difference in results is Crane's single iteration.
