Verification Case 28
PRODUCT: AFT Fathom
TITLE: FthVerify28.fth
REFERENCE: Crane Co., Flow of Fluids Through Valves, Fittings, and Pipe, Technical Paper No. 410, Crane Co., Joliet, IL, 1988, Page 4-1, Example 4-1
FLUID: Water at 80 deg. F
ASSUMPTIONS: Supply pressure is from a 10 feet tank
RESULTS:
| Parameter | Crane | AFT Fathom |
| Reynolds number | 89,600 | 88,780 |
| Friction factor | 0.0182 | 0.01845 |
DISCUSSION:
For the purpose of previous verification help files in AFT Fathom, the inner diameter for the pipe was set to be equivalent to the nominal pipe diameter. The model file was updated to use the actual inner diameter stated by Crane to be 2.067 inches. This causes the AFT Fathom Reynolds number to be closer to Crane's results, but differs from the results shown in the AFT Fathom 10 verification file.
Note this model uses fluid properties from the AFT Standard fluid library. The AFT Standard fluid library was updated in AFT Fathom 12, thus the AFT Fathom results will be slightly different for this verification case when compared to previous versions of AFT Fathom.
