Abstract:
1. A method of predicting a rate of corrosion in a pipe, comprising the steps of: receiving, by a central processing unit (CPU), data corresponding to input parameter values comprising at least one value representative of a water chemistry parameter of fluid flow in the pipe, and at least one value representative of a physical parameter of the fluid flow in the pipe; for each of a plurality of reduction reactions, calculating, by the CPU, representative current-voltage relationship responsive to one or more of the input parameter values represented by the received data; deriving, by the CPU, a summed current-voltage relationship representative of the plurality of reduction reactions; for an oxidation reaction, calculating, by the CPU, a representative current-voltage relationship responsive to one or more of the input parameter values represented by the received data; identifying, by the CPU, a current density value at a balanced operating point of the summed current-voltage relationship representative of the plurality of reduction reactions with respect to the current voltage relationship representative of the oxidation reaction; calculating, by the CPU, a predicted corrosion rate responsive to the identified current density value; and displaying the predicted corrosion rate at a visual display.
