Verification Case 4
PRODUCT: AFT Fathom
TITLE: FthVerify4.fth
REFERENCE: D.S. Miller, Internal Flow Systems, 2nd Ed., 1990, Gulf Publishing Co., Page 197-199
FLUID: Air
ASSUMPTIONS: Air is incompressible
RESULTS:
| Parameter | Miller | AFT Fathom |
| System head loss (m of air) | 40.3 | 40.36 |
| System head loss (mm of water) | 49.6 | 49.64 |
DISCUSSION:
The velocity and diameter are specified. For use in AFT Fathom, this is converted to a flow rate, obtaining 0.8 m3/sec.
The head loss in the pipe in AFT Fathom can be easily obtained from the pipe dP Stag and dH output values.
