Water Mixer Calculator Form
Example Data Table
| Sample | Volume (L) | Temperature (°C) | pH | TDS (mg/L) | Hardness (mg/L) |
|---|---|---|---|---|---|
| RO Water | 4.00 | 24.00 | 6.80 | 25.00 | 10.00 |
| Mineral Water | 2.50 | 30.00 | 7.40 | 320.00 | 150.00 |
| Mixed Output | 6.50 | 26.31 | 7.08 | 138.46 | 63.85 |
Formula Used
1. Total volume: Vtotal = VA + VB
2. Mass of each stream: m = V × density
3. Mixed temperature: Tmix = (mATA + mBTB) / (mA + mB)
4. Mixed TDS: TDSmix = (VATDSA + VBTDSB) / Vtotal
5. Mixed hardness: Hmix = (VAHA + VBHB) / Vtotal
6. Mixed pH: convert each pH to hydrogen ion concentration, average by volume, then convert back using pH = −log10[H+].
7. Target solver: required Water B volume is found by rearranging the weighted average equation for the selected property.
How to Use This Calculator
Enter the labels for both water sources. Add the volume, temperature, pH, TDS, hardness, and density for each stream. Choose blend analysis for a direct mixed result. Choose target solver when you want the required volume of Water B for a chosen target. Press the calculate button. The result box will appear below the header and above the form. Use the CSV button to export tabular values. Use the PDF button to print or save the report as a PDF file from the browser print dialog.
Water Mixer Calculator Guide
Why Water Mixing Matters
Water blending is common in chemistry and process work. Labs often mix purified water with mineralized water. Plants also mix sources to hit quality limits. Temperature can change reaction speed. pH can affect solubility. TDS and hardness can influence scaling and conductivity. A reliable calculator reduces guesswork.
What This Tool Calculates
This water mixer calculator estimates total volume, total mass, blended temperature, blended pH, mixed TDS, and mixed hardness. It also shows dilution factor and stream ratios. These outputs help users compare feed water, rinse water, and prepared solution water before actual mixing. The target mode adds planning support.
Useful Chemistry Applications
You can use this tool for reagent water preparation, cooling water checks, educational mixing exercises, and dilution planning. It is useful when one source is hot and another is cold. It also helps when one stream has high dissolved solids and the other is cleaner. The weighted equations stay simple and practical.
Important Notes
The calculator assumes ideal mixing. It uses weighted averages for TDS and hardness. It uses hydrogen ion concentration for pH blending. Real systems may vary when buffers, salts, or reactions are strong. Density is included for better thermal balance. For critical research, confirm results with lab measurements and proper chemical models.
FAQs
Plain HTML FAQ list without accordion.
1. What does this water mixer calculator do?
It calculates blended water properties from two input streams. It estimates volume, mass, temperature, pH, TDS, hardness, dilution factor, and target addition needs.
2. Is the pH result exact?
No. It is an approximation based on hydrogen ion concentration. Buffered systems or reactive solutions can behave differently after mixing.
3. Why is density included?
Density improves mass and heat balance calculations. This matters when temperature differs and you want a better mixed temperature estimate.
4. Can I use this for RO and mineral water?
Yes. That is a common use case. It helps estimate the final mineral load and blended quality before physical mixing.
5. What is TDS in this calculator?
TDS means total dissolved solids. The tool uses a weighted average by volume to estimate the final concentration after mixing.
6. What does the target solver do?
It estimates how much Water B is needed to reach a chosen target for TDS, temperature, or hardness using weighted average equations.
7. Can this replace lab testing?
No. It is a planning and estimation tool. You should verify important values with actual instruments and validated laboratory procedures.
8. How do I save the result?
