Redlich kwong calculator
WebThe determination of k ij is based on experimental data from binary systems; “k ij ” results from the value that allows the given equation of state (through the expression in 10.12a) to yield the closest match. These values are assumed to be constant (and so are used) when the same two components are part of a more complex multi-component mixture.
