Verification Case 45
PRODUCT: AFT Fathom
TITLE: FthVerify45.fth
REFERENCE: James John, William Haberman, Introduction to Fluid Mechanics, 2nd Ed., 1980, Prentice-Hall, Page 168-169, Example 6.3
FLUID: Water at 25 deg. C
ASSUMPTIONS: Flow rate is 0.01 m3/sec (omitted in problem statement)
RESULTS:
Parameter | John & Haberman | AFT Fathom |
Pressure drop in cast iron pipe (kPa) | 21.81 | 21.90 |
Prssure drop in pipe 2 (kPa) | 13.46 | 13.63 |
DISCUSSION:
Results disagree slightly because John & Haberman read friction factors from a chart, which is less accurate than AFT Fathom's correlation based method.
