The following table provides a summary of the simulation operation in all three modes:

	Process	Fluid Flow	Dynamic
Purpose	Size pipes for required flow rates. Check heat exchanger outlet temperatures.	Determine the actual flow rate distribution though the network.	Not applicable.
Pumps	Estimate pressure rise.	Operate on a performance curve
Pipes	Calculate diameter to check nominal pipe size requirements.	Set the Inside diameter based on nominal pipe size.
Mixers	Use the minimum of inlet pressures.	Set all inlet and outlet pressures the same.
Heat Exchangers	Specify required flow for flow balance. Check outlet temperature.	Calculate actual flow based on reference conditions.
