Verification Case 45

View Model     Problem Statement

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.
