ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–278 VM123 Analysis Assumptions and Modeling Notes The piping system is modeled using a single element of length = 1 + 2 + 3 = 300 ft. The flow, w, is input at the inlet node. The exit pressure is defined to be zero for reference. An iterative solution is required. A friction factor of 0.05 (input for MU) is assumed for a starting value. Results Comparison Target ANSYS Ratio Pressure Drop, lb/ft 6160. 6164.[1] 1.001 Re 708. 708. 1.000 2 1.
