Process mode for the U1 example simulation

The purpose of Process mode is to size the pipes and set the heat exchanger design flow requirement.

• For the each pipe, select the Size parameter so that the diameter margin (D_margin) is positive for each pipe while maintaining cooling water velocities at 4 m/s (12ft/s).

  Alternatively, set the Size parameter to Next Larger NPS so that when you change to Fluid Flow mode, the selected size will be the next larger size compared to the calculated diameter (D).

• For each heat exchanger, specify the required flow rates. As a result, AVEVA Process Simulation calculates the overall flow and the split fraction between the two flow paths.
