Verification Case 33
PRODUCT: AFT Fathom
TITLE: FthVerify33.fth
REFERENCE: Crane Co., Flow of Fluids Through Valves, Fittings, and Pipe, Technical Paper No. 410, Crane Co., Joliet, IL, 1988, Page 4-6, Example 4-11
FLUID: Water at 180 deg. F
ASSUMPTIONS: Inlet pressure is 100 psig.
RESULTS:
| Parameter | Crane | AFT Fathom |
| Pressure drop (psid) | 1.91 | 1.91 |
DISCUSSION:
The total pressure change in AFT Fathom can be found in two places. First, the discharge presssure (98.09 psig) can be subtracted from the inlet pressure (100 psig). Second, the pressure difference is given in the Junction Deltas table at the top of the Output window. The junction delta was setup in the Output Control 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.
