Verification Case 38
PRODUCT: AFT Fathom
TITLE: FthVerify38.fth
REFERENCE: Crane Co., Flow of Fluids Through Valves, Fittings, and Pipe, Technical Paper No. 410, Crane Co., Joliet, IL, 1988, Page 4-12, Example 4-19
FLUID: Water at 60 deg. F
ASSUMPTIONS: N/A
RESULTS:
| Parameter | Crane | AFT Fathom |
| Flow rate (gpm) | 137 | 139 |
DISCUSSION:
Crane used friction factors of 0.021 and 0.020 based on a chart lookup. AFT Fathom calculated friction factors of 0.0201 and 0.0206 for the two pipes based on the Colebrook-White correlation. Crane's slightly larger friction factor from the chart lookup is the reason the results differ slightly.
