Formula
Σ(assayᵢⱼ−targetᵢ) × additionⱼ = initial mass × (targetᵢ−initialᵢ)
Solve simultaneous mass balances with nonnegative additions.
Assumptions & limits
- Mass fractions are wt%, not volume%. Components are conserved; no reaction, evaporation or precipitation.
- Planning calculation only: verify assays, solubility, heat release and handling with a qualified chemist.
- One independent addition feed per constrained component. Carrier is the remaining fraction. Negative additions, rank-deficient and infeasible systems are rejected.
Worked example
For the example inputs: Final batch mass = 121.4286 kg; Total additions = 21.42857 kg.
Σ(assayᵢⱼ−targetᵢ) × additionⱼ = initial mass × (targetᵢ−initialᵢ)
