This calculator shows the temperature of a mixture of two or more quantities or streams of water, each of them at different temperatures.
The procedure it follows is:
Calculates the specific enthalpy: Adds the specific enthalpies of each quantity multiplied by its percentage in weight.
Calculates the specific enthalpy for the mixture.
You can add all the lines you wish, but it is important to be sure that all of them correspond with conditions for liquid water, in order case results will not be correct.
