Verification Case 29
PRODUCT: AFT Fathom
TITLE: FthVerify29.fth
REFERENCE: Crane Co., Flow of Fluids Through Valves, Fittings, and Pipe, Technical Paper No. 410, Crane Co., Joliet, IL, 1988, Page 4-3, Example 4-6
FLUID: Water at 60 deg. F
ASSUMPTIONS: Friction factor in pipe is 0.018.
RESULTS:
| Parameter | Crane | AFT Fathom |
| Velocity (feet/sec) | 8.5 | 8.545 |
| Flow Rate (gal/min) | 196 | 196.9 |
DISCUSSION:
The loss factor for the flanged ball valve was not in the AFT Fathom library, and the resulting K factor of 0.58 was entered directly as a fitting and loss value for pipe 1.
Slight differences in the predictions result from round-off.
