Overview

A species can be given a charge as part of the definition of the species.

The charge is generally for display only.

SysCAD will not enforce or warn about charged streams.

SysCAD will not check the charge balance of a reaction, but the Reaction Editor can (optionally) check the charge balance.

Overall Calculation

The calculation of overall charge of in a stream is performed by addition of the multiplication of species charge by species molar flow for all species, and dividing this by the total molar flow.

  • [math] \cfrac{\sum\limits^{^N}_{x=1} (Charge_x * Moles_x)}{\sum\limits^{^N}_{x=1} (Moles_x)} [/math]
