Fluid mixing calculator
Calculate final temperature, concentration, and approximate density for mixes of multiple streams, with target mode, CSV export, and printable report.
Fluid mixing: final temperature, concentration, and approximate density
Combine multiple streams with energy and mass balance. Includes target mode, detailed table, mini charts, CSV export, and a printable report.
1) Streams
Add N streams, define whether the amount is mass or volume, and select properties (ρ, cp). Duplicate or reorder as needed.
2) Units and assumptions
Basic
If you disable this assumption, volume-based results may not be valid.
