Verification Case 73

View Model    Problem Statement

PRODUCT: AFT Fathom (with SSL Module)

TITLE: FthVerify73.fth

REFERENCE: Wilson, Addie, Sellgren & Clift, Slurry Transport Using Centrifugal Pumps 3rd Edition, 2006, Publisher Springer, Page 243-244, Case Study 10.2

FLUID: Water/Ore

ASSUMPTIONS: Water temperature is assumed to be 4 deg. C. M is assumed to be 1.7. Also, the system configuration is not given (i.e. pressures, pipe lengths, pipe diameters, etc) and were assumed. These assumptions do not affect the final results of the problem. Use simplified slurry calculations. Use ANSI/HI Standard 12.1-12.6-2005 calculations to determine the pump corrections.

RESULTS:

	AFT Fathom	Wilson, Addie, Sellgren & Clift
De-Rating Correction:	6.4%	6.2%

DISCUSSION:

The correction factor calculated in Fathom was CH = 93.6%. This is related to the correction given in Wilson, Addie, Sellgren & Clift by subtracting CH from 100%.
