Verification Case 50
PRODUCT: AFT Fathom
TITLE: FthVerify50.fth
REFERENCE: William S. Janna, Introduction to Fluid Mechanics, 1983, PWS Publishers, Page 166-167, Example 5.3
FLUID: Water at 22 deg. C
ASSUMPTIONS: N/A
RESULTS:
Parameter | John & Haberman | AFT Fathom |
Head loss in pipe (meters) | 0.744 | 0.759 |
Pressure drop in pipe (kPa) | 7.279 | 7.434 |
DISCUSSION:
Results disagree slightly because Janna reads friction factors from a chart, which is less accurate than AFT Fathom's correlation based method. The friction factor was determined to be 0.022 by Janna, and AFT Fathom calculated it as 0.02244 based on the Colebrook-White method, which is 2% higher.
