Comp1FlowReaction

In a single compartment with flow, substrates C and D convert to each other using an equilibrium constraint.

(JSim model applet may take 10-20 seconds to load.)

Description

This is a one compartment model. F is flow, Cin is inflow concentration, Cout and Dout are outflow concentrations, V is volume, kc2d is the rate at which substance C is converted to substance D, and kd2c is the rate at which substance D is converted to substance C. C0 and D0 are the initial concentrations of C and D respectively. The amount of material in the compartment is calculated by multiplying the volume by the sum of the concentrations and also by integrating the flow multiplying the difference of what flows in minus what flows out. Statistics about this system can be calculated on either the sum of Cout plus Dout, or on either substance separately.
