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.

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.
