== General Description ==

The pump model will add pressure boost to the stream or operates at a specified pressure.

== Diagram ==

[[Image:Models-Pump-Image001.gif]]

The diagram shows the default drawing of the Pump, with the required connecting streams. The unit will not operate unless all of the above streams are connected.

The physical location of the connections is not important, the user may connect the streams to any position on the drawing.

==  Model Theory ==

From the first law of thermodynamics, the energy balance is:

<math>\mathbf{\mathit{Work = Enthalpy_{in} - Enthalpy_{out}}}</math>

From the second law of thermodynamics:

<math>\mathbf{\mathit{Entropy_{in} = Entropy_{out}}}</math>

'''Calculating Work:'''

Step 1) Enthalpy and Entropy in is calculated from the inlet stream Temperature and Pressure.

Step 2) Outlet Temperature and Enthalpy is calculated based on the Entropy and outlet pressure.

Step 3) Work is calculated from the difference in enthalpy.

=== Assumptions ===

# The process is in steady state and steady flow.
# The process is adiabatic.
# The change in Potential and Kinetics energy is ignored.
# The process is reversible and adiabatic

== Data Sections ==
=== Summary of Data Sections ===

# '''[[#Pump Page|Pump-1]]''' tab - Contains general information relating to the unit.
# '''[[VLE]]''' - Optional tab, only visible if the VLEquilibrium is enabled in the Evaluation Block.
# '''[[Common Data Sections#Common Data on Info Tab Page|Info]]''' tab - Contains general settings for the unit and allows the user to include documentation about the unit and create Hyperlinks to external documents.
# '''[[Links Table|Links]]''' tab, contains a summary table for all the input and output streams. 
# '''[[Audit]]''' tab - Contains summary information required for Mass and Energy balance. See [[Model Examples]] for enthalpy calculation Examples.
