Mass Balance — Mixer / Junction
2
chemenggcalc.com — multiple inlet streams → one outlet. Basis: mass flow (kg/h).
3
How to use: name up to 3 components, enter each inlet stream's total flow and mass fractions. Outlet is computed; closure checks confirm consistency.

Notes
27
• Outlet is computed directly, so overall and component balances close by construction; the Σw checks catch fraction-entry errors.
28
• Set unused streams or components to zero. Rename components in row 6.
29
• For streams given as component flows instead of fractions, enter total = sum of flows and fractions = flow/total.
