A Water Mixture Temperature Calculator is a simple tool. It finds the final water temperature when two streams mix. You can use it for taps, labs, or kitchens. It works by using volumes and temperatures.
It will add heat from warm water and cool from cold water. Then it divides by total water. You can get a quick result. It helps you set safe bath water or tune a radiator. The math is light. You can do it by hand or use the tool. It makes tasks fast and sure.
When to calculate mixed water temperature
A teacher is showing students how to mix water for an experiment. She has hot water at 80°C and cold at 20°C. She uses 2 L of hot. She uses 3 L of cold. They watch and learn. This example shows why the calc is useful in class and shop.
Calculate the final temperature — step by step
First know formula:
Final Temp = (m₁·T₁ + m₂·T₂) / (m₁ + m₂).
Here m = liters (acts like mass). T = temperature in °C.
Then plug values: m₁ = 2 L, T₁ = 80°C. m₂ = 3 L, T₂ = 20°C.
Now multiply: 2×80 = 160. 3×20 = 60.
Add results: 160 + 60 = 220.
Divide by total volume: 2 + 3 = 5.
So final = 220 ÷ 5 = 44°C.
Thus the mix will read 44°C.
Do the quick add and divide trick if you want a manual check. Still, the calculator saves time and avoids error.
FAQs
What units must I use?
Use same units for both volumes and °C for temp.
Do I need specific heat?
No. For water specific heat cancels, so you can use volumes.
Can I mix more than two streams?
Yes. Sum each (m·T) and divide by total m.
