Pump Main Window
This window is used to supply input data for the pump. The minimum input data requirement is an entry for any one of the Pressure Specification Choices. The Efficiency of the pump is 100% by default. Typical applications fall in the range of 70 - 80%.
Select one of the following parameters and enter its corresponding value:
Outlet Pressure : Pump's outlet pressure.
Pressure Rise : Increase in outlet pressure over the inlet pressure.
Pressure Ratio : Outlet pressure / inlet pressure.
Efficiency
You can change the value from the default of 100% if desired. See Pump Efficiency for more details.
Mechanical Efficiency
You can change the value from the default of 100% if desired. See Mechanical Efficiency for more details.
Alternatively, instead of entering a value for one of the above parameters, the numeric value may be referenced using the Define system relative to any available unit operation or stream parameter calculated elsewhere in the simulation. See Pump Parameters Available for Cross-Referencing for more details.
Complete technical details may be found in topics under Pressure Calculations in the PRO/II Reference Manual.
