Verification Case 35
PRODUCT: AFT Fathom
TITLE: FthVerify35.fth
REFERENCE: Crane Co., Flow of Fluids Through Valves, Fittings, and Pipe, Technical Paper No. 410, Crane Co., Joliet, IL, 1988, Page 4-8, Example 4-14
FLUID: Water at 60 deg. F
ASSUMPTIONS: Inlet pressure is 100 psig
RESULTS:
| Parameter | Crane | AFT Fathom |
| Static Head loss (feet) | 15.8 | 15.5 |
| Static Pressure drop (psid) | 39.0 | 39.22 |
DISCUSSION:
The head loss in AFT Fathom can be found in three places. First, it is given in the pipe output table. Second, it can be obtained by subtracting the discharge HGL from the supply. Third, it can be viewed in the Junction Deltas summary at the top of the Output window. The junction delta was setup in the Output Control window.
The pressure loss in AFT Fathom can be found by subtracting the discharge pressure from the supply. It also can be found in the Junction Deltas on the Output window.
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.
