I'm going to fill a big container (3500 litres) with water. I'll use water from a hose, and boiled water, and I want to hit 40 degrees celcius.
Now, I figured that this was straight forward,
Temperature in hose = 10 C
Temperature of boiled water = 100 C
( 100 * X + (3500 - X) * 10 ) / 3500 = 40
Which gives 1166 litres of boiling water.
However, this assumes that 1 litre of 10 C water + 1 litre of 20 C water = 2 litres of 15 C water. In other words, that I can just add the temperatures together and then divide by the total amount of liquid.
Someone (who unfortunatly was not able to provide a formula) said it is not as straight forward as that.. so, I'm looking for the formula for mixing liquids of different temperatures.
