Verification Case 15
PRODUCT: AFT Impulse 9
TITLE: ImpVerify15.imp
REFERENCE:Fluid Transients in Pipeline, 1988, Nippon Kokan Technical Report, Overseas No. 52, Toshihiko Kamemura, et. al., Page 48, Case B.
FLUID: Water
ASSUMPTIONS: N/A
RESULTS:
DISCUSSION:
All of the results from Impulse were compared to the measured results plotted in figures 13-17 found in the reference. This was accomplished by scanning the figures, and using digitization software to obtain values for the plotted results.
Figures 13-15 in the reference plot the results as Absolute Pressure Head, whereas Impulse plots pressure head as the Hydraulic Gradeline, which is a relative pressure. In the case of Figure 14, the results for Hydraulic Gradeline plotted from Impulse had to be adjusted by 4.56 m to match the absolute pressure head due to the change in pipe elevation at x = 40m.
